fors_extract_objects(7) Extract objects in slit spectra


esorex fors_extract_objects [OPTIONS] FILE.sof


This recipe is used to extract scientific objects spectra on a resampled image produced with recipe fors_resample, at the positions listed in the object table produced by recipe fors_detect_objects. Please refer to the FORS Pipeline User's Manual for more details on object extraction.

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

--ext_mode <long>
Object extraction method: 0 = aperture, 1 = Horne optimal extraction (long; default: 1). The full name of this option for the EsoRex configuration file is fors.fors_extract_objects.ext_mode [default = 1].

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.
