FORTRAN Generation
(/./ftp/cats/J/ApJS/224/18)

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

*  S14 = Solovyov & Verkhodanov 2014AstBu..69..141S
