FORTRAN Generation
(/./ftp/cats/I/107A)

Conversion of standardized ReadMe file for file /./ftp/cats/I/107A 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 2000-epoch positions have nothing to do with the "J2000" system.
*Note (2): The Lick IDS scheme has been continued, so that components
*    referred to in earlier catalogs by small letters, a, b, etc.
*    become upper case P, Q, etc. Thus, Aa becomes AP, Bb becomes BQ, etc.
*Note (3): Position angle in degrees for Date1. For some pairs, the
*    discoverers have given only crude estimates, such as NF or SP;
*    in such cases these are listed. Position angles are unprecessed
*    (i.e. they are for the mean date of observation.)
*Note (4): Separations greater than 99.9 seconds of arc are treated
*    by the codes (bytes 79-80), or in the notes. In cases where no
*    appreciable motion was observed over the duration of observation,
*    only PosAng1 and Sep1 are given.
*Note (5): Units are seconds of arc per 1000 years unless the Code field
*     is 'P' or 'R'. In these cases, the units are seconds of arc per
*     100 years.
*Note (6): The Durchmusterung number is based on the system used by the
*     Henry Draper Catalog: +89 >= BD >= -22; -23 >= CD >= -51;
*     -52 >= CP >= -89. When a star does not follow these standards,
*     it is indicated in the notes.
*Note (7): The notes have the following meaning (see also "doc.ori" file):
*       D: Declination sign change. (Across equator).
*       N: Notes found in the Notes table.
*       O: Orbit. Where motion has exceeded 360 degrees, no values
*          are listed in the position angle and separation fields.
*          Orbits may be found in the "Fourth Catalog of Orbits of
*          Visual Binary Stars" (Worley and Heintz, 1983), and in
*          the Information Circulars published by Commission 26 of
*          the IAU, as well as in the literature.
*       P: 100 year proper motion in right ascension.
*       Q: 100 year proper motion in declination.
*       R: 100 year proper motion in right ascension and declination.
*       1: One hundred seconds to be added to the separation.
*       2: Two hundred seconds to be added to the separation.
*       3: Three hundred seconds to be added to the separation.
*       4: Four hundred seconds to be added to the separation.
*       6: Separation given in minutes of arc rather than seconds.
*       There are also a few non-explained codes:
*         S (record 6838)
*         7 (record 13287)
*         M (record 73490)
