NAME

       uves_obs_redchain - Runs the full UVES reduction chain

SYNOPSIS

       esorex uves_obs_redchain [OPTIONS] FILE.sof

DESCRIPTION

       This recipe does a complete science reduction. It runs all necessary calibration recipes
       depending on the availability of raw/processed calibration frames.

       Input frames are all UVES raw and reference frames: formatchecks, ARC_LAMP_FORM_xxxx,
       xxxx=BLUE or RED, order definition frames, ORDER_FLAT_xxx, biases, BIAS_xxx, darks,
       DARK_xxx, flats, FLAT_xxx, arc lamps, ARC_LAMP_xxx, standard stars, STANDARD_xxx a
       wavelength catalogue table,LINE_REFER_TABLE, and optionally a wavelength table of bright
       lines,LINE_INTMON_TABLE, used only for computing Quality Control parameters.

       a reference standard star flux table, FLUX_STD_TABLE, a table describing the atmospheric
       extintion,EXTCOEFF_TABLE.

       optionally, science frames, SCIENCE_xxx, or UVES_SCI_POINT_xxx, or UVES_SCI_EXTND_xxx, or
       UVES_SCI_SLICER_xxx.

       For further details on the data reduction and the input frame types refer to the man page
       of the individual recipes.

OPTIONS

       --debug <bool>
              Whether or not to save intermediate results to local directory (bool; default:
              False). The full name of this option for the EsoRex configuration file is
              uves.debug [default = False].

       --plotter <str>
              Any plots produced by the recipe are redirected to the command specified by this
              parameter. The plotting command must contain the substring ´gnuplot´ and must be
              able to parse gnuplot syntax on its standard input. Valid examples of such a
              command may include ´gnuplot -persist´ and ´cat > mygnuplot$$.gp´. A finer control
              of the plotting options can be obtained by writing an executable script, e.g.
              my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options
              (e.g. set terminal pslatex color). To turn off plotting, set this parameter to ´no´
              (str; default: ´no´). The full name of this option for the EsoRex configuration

              profile, ´moffat´ gives a Moffat profile with beta=4 and a possible linear sky

              the actual object profile).  ´constant´ assumes a constant spatial profile and
              allows optimal extraction of wavelength calibration frames. ´auto´ will
              automatically select the best method based on the estimated S/N of the object. For
              low S/N, ´moffat´ or ´gauss´ are recommended (for robustness). For high S/N,
              ´virtual´ is recommended (for accuracy). In the case of virtual resampling, a
              precise determination of the order positions is required; therefore the
              order-definition is repeated using the (assumed non-low S/N) science frame (str;
              default: ´auto´). The full name of this option for the EsoRex configuration file is

              the sky as the median of pixels along the slit (ignoring pixels close to the
              object), whereas ´optimal´ does a chi square minimization along the slit to obtain
              the best combined object and sky levels. The optimal method gives the most accurate
              sky determination but is also a bit slower than the median method (str; default:

              (before extraction); if set to ´extract´, flat- fielding is performed in
              pixel-order space (i.e. after extraction). If set to ´no´, no flat-field correction
              is done, in which case reduce.rebin.scale should be set to true to ensure flux
              conservation (both for response and science data) (str; default: ´extract´). The

              If ´sum´, the flux in the overlapping region is computed as the sum of the single
              order spectra. If ´noappend´ the spectrum is simply rebinned but not merged.If
              flat-fielding is done, method ´optimal´ is recommended, otherwise ´sum´. (str;
              default: ´optimal´). The full name of this option for the EsoRex configuration file

       --uves_cal_response.reduce.merge_delt1 <float>
              Order merging left hand (short wavelength) cut. To reduce the amount of order
              overlapping regions we allow to cut short and long wavelength ranges. This may
              reduce the ripple possibly introduced by the order merging. Suggested values are:
              10 (W<=390), 12 (390<W<=437, 520<W<=564), 14 (437<W<=520, 564<W)  (float; default:

              overlapping regions we allow to cut short and long wavelength ranges. This may
              reduce the ripple possibly introduced by the order merging. Suggested values is 4
              (float; default: 0.0). The full name of this option for the EsoRex configuration
              file is uves_obs_redchain.uves_cal_response.reduce.merge_delt2 [default = 0.0].

       --uves_cal_response.reduce.objoffset <float>
              Offset (in pixels) of extraction slit with respect to center of order.  For optimal
              extraction the full slit is offset. For linear/average extraction, reduce.objoffset
              is ignored if reduce.objslit [default -1.0] is negative. In this case the offset is
              automatically determined by measuring the actual object position. (float; default:

              Object window size (in pixels), ignored for optimal extraction. The value must be
              smaller than the total slit length. If negative, the default value (half of full
              slit length) is used. The upper and lower sky windows are defined as the part of
              the full slit (if any) outside the object window. The center of the object window
              is determined by the offset parameter. (float; default: -1.0). The full name of

              Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during
              the rebinning to conserve the flux. This option is disabled as default because
              applying the flat field correction already ensures flux conservation. Therefore
              this parameter should be TRUE (for response and science data) only if
              reduce.ffmethd = no. (bool; default: False). The full name of this option for the

       --uves_cal_response.reduce.slitlength <float>
              Extraction slit length (in pixels). If negative, the value inferred from the raw
              frame header is used (float; default: -1.0). The full name of this option for the

              [default = -1.0].

       --uves_cal_response.reduce.tiltcorr <bool>
              If enabled (recommended), the provided dispersion solutions obtained at different
              slit positions are interpolated linearly at the actually measured position of the
              object/sky. Line tilt correction is currently not supported for 2d extraction, in
              which case the dispersion solution obtained at the middle of the slit is always
              used. (bool; default: True). The full name of this option for the EsoRex
              configuration file is uves_obs_redchain.uves_cal_response.reduce.tiltcorr [default
              = True].

       --uves_cal_wavecal.degree <int>
              Degrees of the global 2d dispersion polynomial. If a negative number is specified,
              the polynomial degrees are automatically selected by starting from (1, 1) and
              inreasing the degrees as long as the RMS residual decreases significantly (int;
              default: 4). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_cal_wavecal.identify.degree [default = 4].

       --uves_cal_wavecal.extract.best <bool>
              (optimal extraction only) If false (fastest), the spectrum is extracted only once.
              If true (best), the spectrum is extracted twice, the second time using improved
              variance estimates based on the first iteration. Better variance estimates slightly
              improve the obtained signal to noise but at the cost of increased execution time
              (bool; default: True). The full name of this option for the EsoRex configuration
              file is uves_obs_redchain.uves_cal_wavecal.extract.best [default = True].

              EsoRex configuration file is uves_obs_redchain.uves_cal_wavecal.extract.chunk
              [default = 32].

       --uves_cal_wavecal.extract.kappa <float>
              In optimal extraction mode, this is the threshold for bad (i.e.  hot/cold) pixel
              rejection. If a pixel deviates more than kappa*sigma (where sigma is the
              uncertainty of the pixel flux) from the inferred spatial profile, its weight is set
              to zero. Range: [-1,100]. If this parameter is negative, no rejection is performed.
              (float; default: 10.0). The full name of this option for the EsoRex configuration
              file is uves_obs_redchain.uves_cal_wavecal.extract.kappa [default = 10.0].

       --uves_cal_wavecal.extract.method <str>
              Extraction method. (2d/optimal not supported by uves_cal_wavecal, weighted
              supported only by uves_cal_wavecal, 2d not supported by uves_cal_response) (str;

              The oversampling factor used for the virtual resampling algorithm. If negative, the
              value 5 is used for S/N <=200, and the value 10 is used if the estimated S/N is >
              200 (int; default: -1). The full name of this option for the EsoRex configuration
              file is uves_obs_redchain.uves_cal_wavecal.extract.oversample [default = -1].

       --uves_cal_wavecal.extract.profile <str>
              In optimal extraction mode, the kind of profile to use. ´gauss´ gives a Gaussian
              profile, ´moffat´ gives a Moffat profile with beta=4 and a possible linear sky
              contribution. ´virtual´ uses a virtual resampling algorithm (i.e. measures and uses
              the actual object profile).  ´constant´ assumes a constant spatial profile and
              allows optimal extraction of wavelength calibration frames. ´auto´ will
              automatically select the best method based on the estimated S/N of the object. For
              low S/N, ´moffat´ or ´gauss´ are recommended (for robustness). For high S/N,
              ´virtual´ is recommended (for accuracy). In the case of virtual resampling, a
              precise determination of the order positions is required; therefore the
              order-definition is repeated using the (assumed non-low S/N) science frame (str;
              default: ´auto´). The full name of this option for the EsoRex configuration file is

       --uves_cal_wavecal.extract.skymethod <str>
              In optimal extraction mode, the sky subtraction method to use.  ´median´ estimates
              the sky as the median of pixels along the slit (ignoring pixels close to the
              object), whereas ´optimal´ does a chi square minimization along the slit to obtain
              the best combined object and sky levels. The optimal method gives the most accurate
              sky determination but is also a bit slower than the median method (str; default:
              ´optimal´). The full name of this option for the EsoRex configuration file is

       --uves_cal_wavecal.length <float>
              Length (in pixels) of each extraction window. This parameter is also equal to the
              seperation of adjacent window centers, causing the extraction windows to always be
              aligned. The parameter is automatically adjusted according to the binning of the
              input raw frame. If negative, the extraction window length is determined
              automatically to cover the full slit (float; default: -1.0). The full name of this
              option for the EsoRex configuration file is
              uves_obs_redchain.uves_cal_wavecal.length [default = -1.0].

       --uves_cal_wavecal.maxerror <float>

              of the global fit exceeds this value (pix) the iteration stops (float; default:
              20.0). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_cal_wavecal.identify.maxerror [default = 20.0].

       --uves_cal_wavecal.maxlines <int>
              Maximum number of lines to detect. If zero, the default value (1600 for BLUE/REDL
              chip; 1400 for REDU chip) is used. (int; default: 0). The full name of this option
              for the EsoRex configuration file is

              chips; 1000 for REDU chip) is used. (int; default: 0). The full name of this option
              for the EsoRex configuration file is
              uves_obs_redchain.uves_cal_wavecal.search.minlines [default = 0].

       --uves_cal_wavecal.nwindows <int>
              Number of extraction windows per trace. The windows will be aligned (i.e. no
              overlap and no spacing between adjacent windows). Unless an offset is specified,
              the middle window(s) is centered on the trace (int; default: 3). The full name of
              this option for the EsoRex configuration file is

              Width (pix) of search window is 2*range + 1. This parameter is automatically
              adjusted according to binning. (int; default: 8). The full name of this option for
              the EsoRex configuration file is uves_obs_redchain.uves_cal_wavecal.search.range
              [default = 8].

              Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during
              the rebinning to conserve the flux. This option is disabled as default because
              applying the flat field correction already ensures flux conservation. Therefore
              this parameter should be TRUE (for response and science data) only if
              reduce.ffmethd = no. (bool; default: False). The full name of this option for the
              EsoRex configuration file is uves_obs_redchain.uves_cal_wavecal.rebin.scale
              [default = False].

       --uves_cal_wavecal.rebin.wavestep <float>
              The bin size used for BLUE/REDL data (in w.l.u.) in wavelength space.  If negative,
              a step size of 2/3 * ( average pixel size ) is used.  (float; default: -1.0). The
              full name of this option for the EsoRex configuration file is

       --uves_cal_wavecal.rebin.wavestep_redu <float>
              The bin size used for REDU data (in w.l.u.) in wavelength space. If negative, a
              step size of 2/3 * ( average pixel size ) is used. (float; default: -1.0). The full
              name of this option for the EsoRex configuration file is

              parameter is automatically corrected for binning (float; default: 10.0). The full
              name of this option for the EsoRex configuration file is

              according to binning (float; default: 0.05). The full name of this option for the
              EsoRex configuration file is uves_obs_redchain.uves_cal_wavecal.first.shifttoler
              [default = 0.05].

       --uves_cal_wavecal.tolerance <float>
              Tolerance of fit. If positive, the tolerance is in pixel units. If negative,
              abs(tolerance) is in wavelength units. Lines with residuals worse than the
              tolerance are excluded from the final fit. Unlike in previous versions, this
              parameter is not corrected for CCD binning.  This rejection based on the absolute
              residual in pixel can be effectively disabled by setting the tolerance to a very
              large number (e.g. 9999). In that case outliers will be rejected using only kappa
              sigma clipping. (float; default: 0.6). The full name of this option for the EsoRex
              configuration file is uves_obs_redchain.uves_cal_wavecal.calibrate.tolerance

              Clean detector traps. If TRUE detector traps are interpolated.The bad pixels are
              replaced by the average of thenearest good pixels in the same column, or simply
              marked as bad. The positions of bad pixels are hard-coded (as function of UVES
              chip). (bool; default: False). The full name of this option for the EsoRex
              configuration file is uves_obs_redchain.uves_obs_scired.clean_traps [default =
              False].

       --uves_obs_scired.reduce.backsub.mmethod <str>

              If spline interpolation is used to measure the background, the y-radius of the
              post-smoothing window is (smoothy * image_height).  Here, ´image_height´ is the

              improve the obtained signal to noise but at the cost of increased execution time

              the sky as the median of pixels along the slit (ignoring pixels close to the
              object), whereas ´optimal´ does a chi square minimization along the slit to obtain
              the best combined object and sky levels. The optimal method gives the most accurate
              sky determination but is also a bit slower than the median method (str; default:
              ´optimal´). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.extract.skymethod [default = optimal].

       --uves_obs_scired.reduce.ffmethod <str>
              Flat-fielding method. If set to ´pixel´, flat-fielding is done in pixel-pixel space
              (before extraction); if set to ´extract´, flat- fielding is performed in
              pixel-order space (i.e. after extraction). If set to ´no´, no flat-field correction
              is done, in which case reduce.rebin.scale should be set to true to ensure flux
              conservation (both for response and science data) (str; default: ´extract´). The
              full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.ffmethod [default = extract].

       --uves_obs_scired.reduce.merge <str>
              Order merging method. If ´optimal´, the flux in the overlapping region is set to
              the (optimally computed, using the uncertainties) average of single order spectra.
              If ´sum´, the flux in the overlapping region is computed as the sum of the single
              order spectra. If ´noappend´ the spectrum is simply rebinned but not merged.If
              flat-fielding is done, method ´optimal´ is recommended, otherwise ´sum´. (str;
              default: ´optimal´). The full name of this option for the EsoRex configuration file
              is uves_obs_redchain.uves_obs_scired.reduce.merge [default = optimal].

       --uves_obs_scired.reduce.merge_delt1 <float>
              Order merging left hand (short wavelength) cut. To reduce the amount of order
              overlapping regions we allow to cut short and long wavelength ranges. This may
              reduce the ripple possibly introduced by the order merging. Suggested values are:
              10 (W<=390), 12 (390<W<=437, 520<W<=564), 14 (437<W<=520, 564<W)  (float; default:
              0.0). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.merge_delt1 [default = 0.0].

       --uves_obs_scired.reduce.merge_delt2 <float>
              Order merging right hand (long wavelength) cut. To reduce the amount of order
              overlapping regions we allow to cut short and long wavelength ranges. This may
              reduce the ripple possibly introduced by the order merging. Suggested values is 4
              (float; default: 0.0). The full name of this option for the EsoRex configuration
              file is uves_obs_redchain.uves_obs_scired.reduce.merge_delt2 [default = 0.0].

       --uves_obs_scired.reduce.objoffset <float>
              Offset (in pixels) of extraction slit with respect to center of order.  For optimal
              extraction the full slit is offset. For linear/average extraction, reduce.objoffset
              is ignored if reduce.objslit [default -1.0] is negative. In this case the offset is
              automatically determined by measuring the actual object position. (float; default:
              0.0). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.objoffset [default = 0.0].

       --uves_obs_scired.reduce.objslit <float>
              Object window size (in pixels), ignored for optimal extraction. The value must be
              smaller than the total slit length. If negative, the default value (half of full
              slit length) is used. The upper and lower sky windows are defined as the part of
              the full slit (if any) outside the object window. The center of the object window
              is determined by the offset parameter. (float; default: -1.0). The full name of
              this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.objslit [default = -1.0].

       --uves_obs_scired.reduce.rebin.scale <bool>
              Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during
              the rebinning to conserve the flux. This option is disabled as default because
              applying the flat field correction already ensures flux conservation. Therefore
              this parameter should be TRUE (for response and science data) only if
              reduce.ffmethd = no. (bool; default: False). The full name of this option for the
              EsoRex configuration file is uves_obs_redchain.uves_obs_scired.reduce.rebin.scale
              [default = False].

       --uves_obs_scired.reduce.rebin.wavestep <float>
              The bin size used for BLUE/REDL data (in w.l.u.) in wavelength space.  If negative,
              a step size of 2/3 * ( average pixel size ) is used.  (float; default: -1.0). The
              full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.rebin.wavestep [default = -1.0].

       --uves_obs_scired.reduce.rebin.wavestep_redu <float>
              The bin size used for REDU data (in w.l.u.) in wavelength space. If negative, a
              step size of 2/3 * ( average pixel size ) is used. (float; default: -1.0). The full
              name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.rebin.wavestep_redu [default = -1.0].

       --uves_obs_scired.reduce.skysub <bool>
              Do sky-subtraction (only applicable to linear and average extractions)? (bool;
              default: True). The full name of this option for the EsoRex configuration file is
              uves_obs_redchain.uves_obs_scired.reduce.skysub [default = True].

       --uves_obs_scired.reduce.slitlength <float>
              Extraction slit length (in pixels). If negative, the value inferred from the raw
              frame header is used (float; default: -1.0). The full name of this option for the
              EsoRex configuration file is uves_obs_redchain.uves_obs_scired.reduce.slitlength
              [default = -1.0].

       --uves_obs_scired.reduce.tiltcorr <bool>
              If enabled (recommended), the provided dispersion solutions obtained at different
              slit positions are interpolated linearly at the actually measured position of the
              object/sky. Line tilt correction is currently not supported for 2d extraction, in
              which case the dispersion solution obtained at the middle of the slit is always
              used. (bool; default: True). The full name of this option for the EsoRex
              configuration file is uves_obs_redchain.uves_obs_scired.reduce.tiltcorr [default =
              True].

       Note that it is possible to create a configuration file containing these options, along
       with suitable default values. Please refer to the details provided by the 'esorex --help'
       command.
