FORTRAN Generation
(/./ftp/cats/J/MNRAS/505/5567)

Conversion of standardized ReadMe file for file /./ftp/cats/J/MNRAS/505/5567 into FORTRAN code for loading all data files into arrays.

Note that special values are assigned to unknown or unspecified numbers (also called NULL numbers); when necessary, the coordinate components making up the right ascension and declination are converted into floating-point numbers representing these angles in degrees.
