NAME

       fors_extract_objects - Extract objects in slit spectra

SYNOPSIS

       esorex fors_extract_objects [OPTIONS] FILE.sof

DESCRIPTION

       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 User´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
       STD.

       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

OPTIONS

       --ext_mode <long>
              Object  extraction  method:  0  =  aperture,  1  =  Horne optimal extraction (long;
              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'
       command.
