FORTRAN Generation
(/./ftp/cats/J/ApJ/598/375)

Conversion of standardized ReadMe file for file /./ftp/cats/J/ApJ/598/375 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.

*Note (4): As described by Gehrels (1986ApJ...303..336G).
*Note (5): Sources with KS>1.7 are variable (see text).
*Note (6): Time-averaged values for sources with >=90 counts as determined
*          from spectral fits with 1T VAPEC optically thin plasma model using
*          a fixed iron abundance Fe=0.3 solar (errors are 90% confidence).
*Note (7): An upper or lower 90% confidence error of +0.0 or -0.0 is quoted
*          when the error calculation algorithm did not converge and no valid
*          90% confidence error was obtained.
*Note (8): As determined from source event list (see text).
*Note (9): At d=415pc as determined from spectral fits of brighter sources
