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 STD.

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].
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].
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.

An overview over the existing ESO pipelines can be found on the web page http://www.eso.org/sci/software/pipelines/.
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 http://packages.python.org/python-cpl/index.html for further information.
