       fors_extract_objects - Extract objects in slit spectra


       esorex fors_extract_objects [OPTIONS] FILE.sof


       This  recipe  is  used to extract scientific objects spectra on a resampled image produced
       with recipe fors_resample, at the positions listed in the object table produced by  recipe
       fors_detect_objects.  Please  refer to the FORS Pipeline UserĀ“s Manual for more details on
       object extraction.

       In the table below the MXU acronym can be alternatively read as MOS and LSS,  and  SCI  as

       Input files:

         DO category:               Type:       Explanation:         Required:
         MAPPED_SCI_MXU             Calib       Resampled slit spectra  Y
         MAPPED_SKY_SCI_MXU         Calib       Resampled sky spectra   Y
         OBJECT_TABLE_SCI_MXU       Calib       Object table            Y

       Output files:

         DO category:               Data type:  Explanation:
         REDUCED_SCI_MXU            FITS image  Extracted object spectra
         REDUCED_SKY_SCI_MXU        FITS image  Extracted sky spectra
         REDUCED_ERROR_SCI_MXU      FITS image  Error on extracted spectra


       --ext_mode <int>
              Object extraction method: 0 = aperture, 1 = Horne optimal extraction (int; default:
              1).  The  full  name  of  this  option  for  the  EsoRex  configuration   file   is
              fors.fors_extract_objects.ext_mode [default = 1].

       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'


       The  full  documentation  for  the fors pipeline can be downloaded as a PDF file using the
       following URL:


       An  overview  over  the  existing  ESO  pipelines  can  be   found   on   the   web   page

       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 for further information.
