fors_resample7

Usage

Overview

This recipe is used to resample at constant wavelength step spatially rectified spectra. The input frames are produced using either the recipe fors_extract_slits in the case of MOS/MXU multi slit exposures, or the recipes fors_remove_bias and fors_flatfield in the case of LSS or long-slit like MOS/MXU data. Only in case of LSS or LSS-like data the SLIT_LOCATION table is required in input. Please refer to the FORS Pipeline User´s Manual for more details.

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

Options

--dispersion <float>

Expected spectral dispersion (Angstrom/pixel) (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.dispersion [default = 0.0].

--startwavelength <float>

Start wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.startwavelength [default = 0.0].

--endwavelength <float>

End wavelength in spectral extraction (float; default: 0.0). The full name of this option for the EsoRex configuration file is fors.fors_resample.endwavelength [default = 0.0].

--flux <bool>

Apply flux conservation (bool; default: True). The full name of this option for the EsoRex configuration file is fors.fors_resample.flux [default = True].

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.
