FORTRAN Generation
(/./ftp/cats/I/252)

Conversion of standardized ReadMe file for file /./ftp/cats/I/252 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.

*Note on USNO-A2.0:
*    This number allows to retrieve the exact original record: it is made
*    of a zone number (4 digits from 0000 to 1725 representing the distance
*    in 0.1deg to the South Pole, stepped by 75 = 7.5degrees), a dash (-)
*    and a number in the area (8 digits, order by IRCS (J2000) RA);
*    ****Note that this number differs from the USNO-A1.0 one.
*Note on Epoch:
*    Epoch is the averaged date of observation between the blue and
*    the red plates.
