The visir_util_spc_std_cat recipe
===============================================================

.. data:: visir_util_spc_std_cat

Synopsis
--------

Generate a FITS catalog of spectroscopic standard stars

Description
-----------

This recipe shall be used to generate a FITS catalog of spectroscopic standard stars for the VISIR pipeline.

The sof file shall consist of lines with the name of an ASCII-file named  <Star_Name>.txt, e.g. HD133165.txt and the tag SPC_CAT_ASCII.

All input ASCII-files must comprise the same number of lines.

The first line of the ASCII-file must have 6 fields separated by white-space.

The first three fields are the RA (hh mm ss) which will be stored in degrees in a table column labeled 'RA' - all three are non-negative and hh and mm are integer.

The 3 last fields are the DEC (dd mm ss) which will be stored in degrees in a table column labeled 'DEC' - all three are non-negative, dd and mm are integer, and dd has either a '+' or a '-' prepended (including -00).

The remaining lines must all consist of two fields separated by white-space.

The first field is the wavelength (in microns) and the second the (positive) model flux in W/m2/m. The wavelengths must be identical in all the input files.
