Conversion of standardized ReadMe file for
file /./ftp/cats/J/A_A/642/A150 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 (2): The Group column flags the different subsamples as follows:
* 1 = XMM-Newton z~3 sample
* 2 = new XMM-Newton z~4 quasar
* 3 = High-z sample
* 4 = XXL
* 5 = SDSS - 4XMM
* 6 = SDSS - Chandra
* 7 = local AGN
*Note (3): The column DM reports the distance moduli to reproduce Fig.9
