NAME¶

fors_extract_objects - Extract objects in slit spectra

SYNOPSIS¶

esorex fors_extract_objects [OPTIONS] FILE.sof

DESCRIPTION¶

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.

Input files:

DO category: Type: Explanation: Required:
MAPPED_SCI_MXU Calib Resampled slit spectra Y
MAPPED_SKY_SCI_MXU Calib Resampled sky spectra Y
OBJECT_TABLE_SCI_MXU Calib Object table Y

Output files:

DO category: Data type: Explanation:
REDUCED_SCI_MXU FITS image Extracted object spectra
REDUCED_SKY_SCI_MXU FITS image Extracted sky spectra
REDUCED_ERROR_SCI_MXU FITS image Error on extracted spectra

OPTIONS¶

--ext_mode <int>

Object extraction method: 0 = aperture, 1 = Horne optimal extraction (int; 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.
