FORTRAN Generation
(/./ftp/cats/J/AJ/126/2562)

Conversion of standardized ReadMe file for file /./ftp/cats/J/AJ/126/2562 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.

*          data used for the position determination;
*    X+  = Only X-band group delays were used, because of the poor quality
*          of the S-band data;
*    X-o = Only X-band group delays were used, because no fringes at S
*          band were detected.
*Note (3): Quality factor:
*    1 = Excellent quality. Little change of signal over all baselines and
*        stronger than 0.4Jy.
*    2 = Good quality. Some decrease of signal at shorter baselines, but
*        stronger than 0.2Jy at all baselines.
*    3 = Average quality. Decrease of signal at the shorter baselines, but
*        stronger than 0.10Jy everywhere.
*    4 = Fair quality. Less than 0.10Jy on the longer baselines, but more
*        signal on the shorter baselines. These calibrators should be
*        checked before using.
*    5 = Poor quality. Less than 0.10Jy on most baselines. These
*        calibrators should not be used. The positions could be even more
*        in error than indicated. Most sources within about 10 degrees of
*        the Galactic plane are significantly broadened by interstellar
*        scattering at 2.3GHz.
*    ? = Unknown quality.
