Conversion of standardized ReadMe file for
file /./ftp/cats/J/ApJ/598/969 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.

real*4 e_HR2 (nr__) ! ? rms uncertainty on HR2
character*1 Band (nr__) ! [BSH] Band in which a source is detected with
* the most accurate position (2)
*Note (1): The false detection probability P that the detected number of
* counts may result from the Poisson fluctuation of the local background
* within the detection aperture (logP<-20.0 is set to -20.0).
*Note (2): Hardness ratios are defined by:
* S1 = net source count rates in the 0.3-0.7keV band
* S2 = net source count rates in the 0.7-1.5keV band
* H1 = net source count rates in the 1.5-3keV band
* H2 = net source count rates in the 3-7keV band
* S = S1+S2, H = H1+H2, B = S+H
* The hardness ratios are calculated only for sources with individual
* S/Ns greater than 4 in the broad band (B=S+H), and only the values
* with uncertainties less than 0.2 are included
