Conversion of standardized ReadMe file for
file /./ftp/cats/J/ApJS/224/18 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): Coordinate based source designations are truncated, not rounded.
*Note (2): It should be noted that only the coordinates associated with a NVSS
* catalog entry have the significance of the NVSS entry.
* GRS previously identified by Lara et al. (2001, J/A+A/370/409),
* Machalski et al. (2001A&A...371..445M), and
* Solovyov & Verkhodanov (2014AstBu..69..141S), were retained
* but not given an NVGRC designation. Coordinates are given as for
* other entries.
* Flag as follows:
* c = system coordinate is a NVSS fitted catalog entry (557 sources);
* v = coordinate is visual estimate from symmetry considerations;
*Note (3): Approximately two dozen candidates less that 4.0' were retained in
* the table for documentation purposes.
*Note (4): Although the training set consisted of primarily FRI and FRII type
* sources, FR classification was not attempted. Though many of the
* larger "d" and "t" annotated systems are clearly FRII, the smaller,
* less resolved sources were difficult to evaluate. It was felt such
* distinctions deserved more uniform analytic attention. Also note
* that other morphological types were retained for documentation
* purposes. Key to annotations:
* amb = ambiguous;
* arc = arc or C-shape, possible edge brightened lobe, bent jets,
* or ring fragment;
* cj = core-jet;
* d = double lobe radio galaxy - may include core-jet sources;
* dd = double double morphology (DD), may be candidate DDRG;
* dl = dogleg;
* fishtail = multiple (usually two) lower level tails;
* hymor = hybrid morphology radio source(s) (HYMORS);
* int = interesting;
* irr = irregular, distorted;
* incidental = non-source pair systems found during cutout examinations;
* jet = protrusion away from presumed core;
* lobe = lobe, resolved lobe;
* mg = multiple groupings possible;
* nat = narrow angle tail (NAT);
* point = non-extended source for which the major and minor axes appear
* to be the same size;
* rc = resolved compact source, non-pointlike;
* ring = ring;
* ring-lobe = edge or rim brightened lobe or embedded ring;
* s = single source (sometimes with sidelobes) or probable chance
* projection of point-like source into group;
* sz = S or Z-shaped;
* t = triple, no bend, little extended structure;
* tail = protrusion (normally lower level) from lobe in direction
* away from core;
* unu = unusual, uncommon - may be due to chance projection;
* w = W-shape, wiggles;
* wat = wide angle tail (WAT);
* x = X-shape
*Note (5): Reference as below:
* S14 = Solovyov & Verkhodanov 2014AstBu..69..141S
* M01 = Machalski et al. 2001A&A...371..445M; <[MJZ2001] JHHMM+DDMM> in Simbad.
* L01 = Lara et al. 2001, J/A+A/370/409; <[LCF2001] JHHMM+DDd> in Simbad.
