Conversion of standardized ReadMe file for
file /./ftp/cats/J/AJ/128/1501 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 (1): The numbers correspond to ascending order of right ascension.
*Note (2): Source name follows the IAU convention and should read CXCCLASXS,
* plus the name given in the table.
*Note (3): In units of 10^-15^ergs/cm^2^/s. If a source is detected
* in multiple observations, and if there is more than one observation in
* which the source effective area is more than 80% of the effective area
* at the aim point, then the mean flux is used; otherwise, the flux from
* the observation that has the largest effective area is used. The
* errors quoted are the 1{sigma} upper and lower Poisson errors, using
* the approximations from Gehrels (1986ApJ...303..336G). For any source
* detected in one band but with a very weak signal in another, the
* background- subtracted flux could be negative. In this case, only the
* upper Poisson error is quoted.
*Note (4): HR=C_Hard_/C_Soft_, where C_Hard_ and C_Soft_ are the count rates
* in the hard and soft bands.
