FORTRAN Generation
(/./ftp/cats/J/MNRAS/439/354)

Conversion of standardized ReadMe file for file /./ftp/cats/J/MNRAS/439/354 into FORTRAN code for reading data files line by line.

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.
