Conversion of standardized ReadMe file for
file /./ftp/cats/J/ApJ/685/773 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 Chandra or XMM-Newton observation identification number.

*Note (5): Where log(R*)=log[L_{nu}_(5GHz)/L_{nu}_(2500{AA})]. We classify
* sources with log(R*)>=1 as "radio-loud" and all other sources as
* "radio-quiet".
*Note (6): Similar to the traditional "balnicity index", BI, of Weymann et
* al. (1991ApJ...373...23W), except that it is integrated from velocity
* offsets -25000km/s to 0km/s from the QSO rest frame.
*Note (7): Found using the method described in Section 2.2.
*Note (8): Where the luminosity is in units of erg/s/Hz.
*Note (9): Where a.OX = {alpha}OX = 0.3838*log(L(2keV)/L(2500{AA})).
*Note (10): Errors assumed to be dominated by the error on X-ray luminosity.
*Note (11): Relative to "ordinary" QSOs. Where
* Da.OX = {Delta}{alpha}OX = {alpha}OX -
* (-0.217+/-0.036)*log(L_2500{AA}_)+(5.075+/-1.118).
* (for instance, a value of -0.5 corresponds to X-ray weakness
* by a factor of ~20 compared to QSOs with the same UV luminosity)
