.SH NAME
fors_extract_objects \- Extract objects in slit spectra

.SH SYNOPSIS
esorex
.B fors_extract_objects
[OPTIONS] FILE.sof

.SH 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.

.SH OPTIONS
.TP
\fB\-\-ext_mode\fR \fI<int>\fR
Object extraction method: 0 = aperture, 1 = Horne optimal extraction
(int; default: 1). The full name of this option for the EsoRex configuration
file is \fBfors.fors_extract_objects.ext_mode\fR [default = \fI1\fR].

.PP
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.
