Convert ASCII-file(s) to a FITS standard star catalog
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.
Create an object for the recipe visir_util_img_std_cat.
