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 <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' command.
