Conversion of standardized ReadMe file for
file /./ftp/cats/J/AJ/151/79 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): The coordinates are from the latest version of the Goddard Space

* Reference Systems Service (IERS) format (status: 01 September 1 2015).
*Note (2): The uncertainties for e_RAs are not corrected from cos(DE). The formal
* errors in the table come directly from the GSFC solution and are likely to
* optimistic. A more realistic estimate would be obtained by applying a scale
* factor of 1.5 to the formal uncertainties followed by a root-sum-square
* increase of 40 micro-arcseconds of error in quadrature to the quoted
* values. This was the procedure adopted for ICRF2 (Fey et al. 2009,
* http://www.iers.org/TN35; Fey et al. 2015, cat. J/AJ/150/58).
*Note (3): The flux values are from sked flux catalog
* (ftp://gemini.gsfc.nasa.gov/pub/sked/catalogs/flux.cat;
* status: 28 August 2015) and from the Bordeaux Very Long Baseline
* Interferometry (VLBI) Image Database (BVID; Collioud & Charlot 2009 Proc.
* 19th EVGA Working Meeting, European VLBI for Geodesy and Astrometry ed
* G. Bourda, P. Charlot and A. Collioud 19; status: 11 September 2015).
* The fluxes are computed from data available through 2015 August 27 for the
* sked catalog and through 2013 July 24 for BVID (see Section 4.3).
*Note (4): The categories are defined as below:
* 1 = One of 89 sources in the IVS source monitoring program that were
* sufficiently observed;
* 2 = One of 66 sources in the IVS source monitoring program that were not
* sufficiently observed;
* 3 = One of 16 sources not in the IVS source monitoring program but with a
* sufficient position accuracy;
* 4 = One of 24 sources not in the IVS source monitoring program and with
* poor position accuracy.
