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

* used; smaller regions were used for some closely-spaced sources.
*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).

* where an estimate of NH and kT is available.
