NAME

       flames_obs_redchain - Runs the full UVES-FIBRE reduction chain

SYNOPSIS

       esorex flames_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-FIBER raw and reference frames: formatchecks, FIB_ARC_LAMP_FORM_RED, order
       definition frames, FIB_ORDER_FLAT_RED, biases, BIAS_RED, darks, DARK_RED, flats, SFLAT_RED, arc lamps,
       FIB_ARC_LAMP_RED, standard stars, FIB_STANDARD_RED 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

       --scired <bool>
              Whether  or  not to do science reduction. If false, only master calibration frames are created. If
              false, either zero or all necessary calibration frames  must  be  provided  for  each  arm  (bool;
              default:   True).   The   full   name  of  this  option  for  the  EsoRex  configuration  file  is
              flames_obs_redchain.scired [default = True].

       --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 file is uves.plotter  [default  =

       --flames_cal_wavecal.nwindows <long>
              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 (long; default: 1). The full name of this option for the EsoRex configuration file is
              flames_obs_redchain.flames_cal_wavecal.nwindows [default = 1].

       --flames_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: 7.0).

       --flames_cal_wavecal.minlines <long>
              Minimum  number of lines to detect. If zero, the default value (1100 for BLUE/REDL chips; 1000 for
              REDU chip) is used. (long; default: 0). The full name of this option for the EsoRex  configuration
              file is flames_obs_redchain.flames_cal_wavecal.search.minlines [default = 0].

       --flames_cal_wavecal.shiftstep <float>
              The step size (pix) used when searching for the optimum shift.  This  parameter  is  automatically
              corrected  for  binning  (float;  default:  0.1).  The  full  name  of  this option for the EsoRex
              configuration file is flames_obs_redchain.flames_cal_wavecal.first.shiftstep [default = 0.1].

       --flames_cal_wavecal.shifttoler <float>
              Tolerance (pix) when matching shifted lines. This parameter is not adjusted according  to  binning
              (float;  default:  0.05).  The  full  name  of  this  option  for the EsoRex configuration file is

       --flames_cal_wavecal.alpha <float>
              The parameter that controls the distance to the nearest neighbours (float; default: 0.1). The full
              name     of     this     option      for      the      EsoRex      configuration      file      is
              flames_obs_redchain.flames_cal_wavecal.identify.alpha [default = 0.1].

       --flames_cal_wavecal.maxerror <float>
              This  parameter  controls  the graceful exit of the identification loop.  If the RMS 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
              flames_obs_redchain.flames_cal_wavecal.identify.maxerror [default = 20.0].

       --flames_cal_wavecal.degree <long>
              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 (long; default: 4). The full name of this option for  the
              EsoRex configuration file is flames_obs_redchain.flames_cal_wavecal.identify.degree [default = 4].

       --flames_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
              flames_obs_redchain.flames_cal_wavecal.calibrate.tolerance [default = 0.6].

       --flames_cal_wavecal.kappa <float>

       --flames_cal_wavecal.rebin.wavestep <float>
              The bin size (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 flames_obs_redchain.flames_cal_wavecal.rebin.wavestep [default = -1.0].

       --flames_cal_wavecal.rebin.scale <bool>
              Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during the  rebinning.
              This option is disabled as default in concordance with the method used in the MIDAS pipeline. This
              option  should  be  set  to  true  to  convert  the  observed  flux (in pixel-space) to a flux per
              wavelength (in wavelength-space). (bool; default: False). The full name of  this  option  for  the
              EsoRex configuration file is flames_obs_redchain.flames_cal_wavecal.rebin.scale [default = False].

       --flames_cal_wavecal.extract.method <str>

              uves_cal_wavecal, 2d not supported by uves_cal_response) (str; default: ´average´). The full  name
              of       this       option       for       the       EsoRex       configuration       file      is
              flames_obs_redchain.flames_cal_wavecal.extract.method [default = average].

       --flames_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  flames_obs_redchain.flames_cal_wavecal.extract.kappa  [default  =
              10.0].

       --flames_cal_wavecal.extract.chunk <long>
              In  optimal extraction mode, the chunk size (in pixels) used for fitting the analytical profile (a
              fit of the analytical profile to single bins would suffer from low  statistics).  (long;  default:
              32).    The    full    name    of   this   option   for   the   EsoRex   configuration   file   is
              flames_obs_redchain.flames_cal_wavecal.extract.chunk [default = 32].

       --flames_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
              flames_obs_redchain.flames_cal_wavecal.extract.profile [default = auto].

       --flames_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 flames_obs_redchain.flames_cal_wavecal.extract.skymethod [default = optimal].

       --flames_cal_wavecal.extract.oversample <long>
              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  (long;  default:  -1).
              The    full    name    of    this    option    for    the    EsoRex    configuration    file    is
              flames_obs_redchain.flames_cal_wavecal.extract.oversample [default = -1].

       --flames_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 flames_obs_redchain.flames_cal_wavecal.extract.best [default = True].

       --flames_obs_scired.ext_method <str>
