visir_util_spc_txt2fits - Generate spectrum calibration FITS tables


esorex visir_util_spc_txt2fits [OPTIONS] FILE.sof


This recipe shall be used to generate spectrum calibration tables.

The sof file shall consist of 1 line with the name of an ASCII-file currently tagged with either SPC_LINES_ASCII or SPC_QEFF_ASCII.

The file must comprise two columns: 1st: Must be wavelengths in increasing order in units of meter 2nd: For SPC_LINES_ASCII-files must be the atmospheric emission, while
for SPC_QEFF_ASCII-files must be the quantum efficiency of the detector.

A SPC_LINES_ASCII-file will generate a SPEC_CAL_LINES-file, and a SPC_QEFF_ASCII-file will generate a SPEC_CAL_QEFF-file.

The current SPEC_CAL_LINES- and SPEC_CAL_QEFF-files are generated using the ASCII-files in the catalogs/ directory of the VISIR source-code distribution.


Ignored (float; default: 1.0). The full name of this option for the EsoRex configuration file is visir.visir_util_spc_txt2fits.qeff [default = 1.0].

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.

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 for further information.
