NAME

       fors_detect_objects - Detect objects in slit spectra

SYNOPSIS

       esorex fors_detect_objects [OPTIONS] FILE.sof

DESCRIPTION

       This  recipe  is  used  to  detect  scientific  objects spectra on a resampled image produced with recipe
       fors_resample. Please refer to the FORS Pipeline User´s Manual for more details on object detection.

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

OPTIONS

       --slit_margin <long>
              Number of pixels to exclude at each slit in object detection and extraction  (long;  default:  3).
              The    full    name    of    this    option    for    the    EsoRex    configuration    file    is
              fors.fors_detect_objects.slit_margin [default = 3].

       --ext_radius <long>
              Maximum extraction radius for detected objects (pixel) (long; default: 6). The full name  of  this
              option for the EsoRex configuration file is fors.fors_detect_objects.ext_radius [default = 6].

       --cont_radius <long>
              Minimum  distance  at  which two objects of equal luminosity do not contaminate each other (pixel)
              (long; default:  0).  The  full  name  of  this  option  for  the  EsoRex  configuration  file  is
              fors.fors_detect_objects.cont_radius [default = 0].

       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.
