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.
