muse_lsf - Compute the LSF
esorex muse_lsf [OPTIONS] FILE.sof
Compute the slice and wavelength dependent LSF from a lines spectrum (ARC lamp).
--nifu <long> IFU to handle. If set to 0, all IFUs are processed serially. If set to -1, all IFUs are processed in parallel. (long; default: 0). The full name of this option for the EsoRex configuration file is muse.muse_lsf.nifu [default = 0]. --overscan <str> If this is "none", stop when detecting discrepant overscan levels (see ovscsigma), for "offset" it assumes that the mean overscan level represents the real offset in the bias levels of the exposures involved, and adjusts the data accordingly; for "vpoly", a polynomial is fit to the vertical overscan and subtracted from the whole quadrant. (str; default: ´vpoly´). The full name of this option for the EsoRex configuration file is muse.muse_lsf.overscan [default = vpoly]. --ovscreject <str> This influences how values are rejected when computing overscan statistics. Either no rejection at all ("none"), rejection using the DCR algorithm ("dcr"), or rejection using an iterative constant fit ("fit"). (str; default: ´dcr´). The full name of this option for the EsoRex configuration file is muse.muse_lsf.ovscreject [default = dcr]. --ovscsigma <float> If the deviation of mean overscan levels between a raw input image and the reference image is higher than |ovscsigma x stdev|, stop the processing. If overscan="vpoly", this is used as sigma rejection level for the iterative polynomial fit (the level comparison is then done afterwards with |100 x stdev| to guard against incompatible settings). Has no effect for overscan="offset". (float; default: 30.0). The full name of this option for the EsoRex configuration file is muse.muse_lsf.ovscsigma [default = 30.0]. --ovscignore <long> The number of pixels of the overscan adjacent to the data region of the CCD that are ignored when computing statistics or fits. (long; default: 3). The full name of this option for the EsoRex configuration file is muse.muse_lsf.ovscignore [default = 3]. --save_subtracted <bool> Save the pixel table after the LSF subtraction. (bool; default: False). The full name of this option for the EsoRex configuration file is muse.muse_lsf.save_subtracted [default = False]. --line_quality <long> Minimal quality flag in line catalog for selection (long; default: 3). The full name of this option for the EsoRex configuration file is muse.muse_lsf.line_quality [default = 3]. --lsf_range <float> Wavelength window (half size) around each line to estimate LSF (float; default: 7.5). The full name of this option for the EsoRex configuration file is muse.muse_lsf.lsf_range [default = 7.5]. --lsf_size <long> Image size in LSF direction (long; default: 150). The full name of this option for the EsoRex configuration file is muse.muse_lsf.lsf_size [default = 150]. --lambda_size <long> Image size in line wavelength direction (long; default: 30). The full name of this option for the EsoRex configuration file is muse.muse_lsf.lambda_size [default = 30]. --lsf_regression_window <float> Size of the regression window in LSF direction (float; default: 0.7). The full name of this option for the EsoRex configuration file is muse.muse_lsf.lsf_regression_window [default = 0.7]. --merge <bool> Merge output products from different IFUs into a common file. (bool; default: False). The full name of this option for the EsoRex configuration file is muse.muse_lsf.merge [default = False]. --combine <str> Type of lampwise image combination to use. (str; default: ´sigclip´). The full name of this option for the EsoRex configuration file is muse.muse_lsf.combine [default = sigclip]. --method <str> LSF generation method. Depending on this value, either an interpolated LSF cube is created, or a table with the parameters of a hermitean gaussian. (str; default: ´interpolate´). The full name of this option for the EsoRex configuration file is muse.muse_lsf.method [default = interpolate]. 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.
The full documentation for the muse pipeline can be downloaded as a PDF file using the following URL: ftp://ftp.eso.org/pub/dfs/pipelines/muse/muse-pipeline-cookbook-1.2.1.pdf An overview over the existing ESO pipelines can be found on the web page http://www.eso.org/sci/software/pipelines/. Basic documentation about the EsoRex program can be found at the esorex (1) man page. It is possible to call the pipelines from python using the python-cpl package. See http://packages.python.org/python-cpl/index.html for further information.
