fors_resample (7)

esorex fors_resample [OPTIONS] FILE.sof

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.

--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.

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.
