       fors_detect_objects - Detect objects in slit spectra


       esorex fors_detect_objects [OPTIONS] FILE.sof


       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

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

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

       --cont_radius <int>
              Minimum distance at which two objects of equal luminosity do not  contaminate  each
              other  (pixel)  (int;  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'

       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.
