Conversion of standardized ReadMe file for
file /./ftp/cats/VII/298 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.

*Note (1): See definitions in class.dat file.
*Note (2): Note as follows:
* a = (0.5-1.5)
*Note (3): magnitude, usually in the V range unless otherwise indicated.
* The "O" magnitude is that measured on the "O" plates of the Palomar
* Observatory Sky Survey (POSS) or obtained from the USNO-A2 or APM Catalogues
* and is related to the B of the Johnson and Morgan system by the following
* relationship: B-O = -(0.27+/-0.06)(B-V) and must therefore be considered with
* care both due to its low intrinsic precision and the variability inherent in
* many quasars. The "r", "i" and "z" magnitudes are provisionally deduced from
* the corresponding bands in the SDSS survey, while those represented with AB
* refer to measurements made at 1450 (1+z) m. For the "cQ" and "bQc" objects
* the magnitudes are sometimes expressed in the "i" band - the symbol of which
* is not always indicated.
*Note (4): Names by which the object is best known from the various catalogs.
* Where catalog abbreviations are followed by coordinates, these are reported
* only once to avoid cluttering the column, also considering that the
* coordinates themselves are often provided with different precisions and
* styles depending on the publications in which they appear.
*
* For the meanings of the various acronyms and abbreviations, see acro.dat file.
* In the case of "cQ" and "bQc," only the relevant catalog number or reference
* to the respective survey has been included. In this regard, please note that
* the "cQ" and "bQc" have been included anyway, even if their coordinates,
* in many cases, correspond to those of objects already included previously.
* In these cases, a progressive consolidation is underway.
*
* The same applies to objects included in the LQAC, LQRF, and APK catalogs.
* Since the existing catalogs were compiled at very different times and with
* technologies of varying precision in multiple spectral regions, we opted
* - in identifying the various acronyms - for an error radius of 10" which
* represents a good compromise for both the old catalogs and the first space
* surveys (IR, UV, X-ray, Gamma); this means that, especially for the latter,
* correspondences should be treated with caution.
*Note (5): The acronym QUAC means that the finding chart of the object is
* available in the Atlas section.
