Synopsis

Convert ASCII-file(s) to a FITS standard star catalog

Description

This recipe generates a FITS standard star catalog for imaging from one or more ASCII-files.

Each line in the text file must have 45 fields separated by white-space.

The first field is the star name, e.g. ‘HD108903’ which will be stored in a table column labeled ‘STARS’.

The 3 next 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 next 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, while dd has either a ‘+’ or a ‘-‘ prepended (including -00).

The next field is the spectral type which will be stored in a table column labeled ‘SP_TYPE’.

The 31 next fields are the JY values for the 31 supported image filters.

The 6 next fields are the JY values for the 6 supported spectral filters.

All JY values must be positive.

For each filter the JY value is stored in a table column labeled with the filter name.

The 37 filter names are hard-coded in the recipe.

Lines beginning with a hash (#) are treated as comments.

The ASCII-input should be tagged IMG_LINES_ASCII, but all input files will currently be processed regardless.
