Conversion of standardized ReadMe file for
file /./ftp/cats/B/wds into FORTRAN code for loading all data files into arrays.
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): Components, when the object has more than two. The Lick IDS
* scheme (which used letters P, Q, R...) has been discontinued, and
* components are now referred to by the traditionally employed
* lower-case letters. The rather awkward upper-case designations, e.g.
* ABXC, have been changed to the form AB-C, etc. We have noted some
* confusion on the part of observers and students alike, as to how to
* designate components in multiple systems. Traditionally, these have
* been designated in order of separation, thus AB, AC,...., or in the
* cases where close pairs are observed blended, AB-C, AB-D,.... In some
* instances, differing resolution limits produce situations where
* observations are intermixed, thus AC, AB-C, and so forth (in all too
* many cases, carelessness on the part of the observer does not permit
* us to determine with certainty how the observation is to be
* interpreted). There are also many instances where later observations
* have revealed a closer companion; these are designated Aa, Bb, etc.
* In a few cases wider, later discoveries have also been so denoted.
*Note (2): Crude positions (e.g., NP for "North Preceding") of the past have
* been changed to their degree equivalent with an accompanying note.
* Position angles are unprecessed in this catalog (i.e., they are for
* the mean date of observation).
*Note (3): use the convention of the Henry Draper Catalogue:
* BD (Bonn) from +89 degrees to -22 degrees inclusive, Cordoba from -23
* degrees to -51 degrees inclusive, Cape Photographic from -52 degrees
* to -89 degrees inclusive. When a star is not contained in the
* Durchmusterung proper to its declination zone, but is contained in
* another Durchmusterung, this is so indicated in the Notes. Other
* components having different Durchmusterung numbers are also indicated
* in the Notes. From September 2009, the DM number may be followed by
* a component letter, e.g. "-50 9826B" for WSI 81Ba,Bb
*Note (4): The following codes are contained in these columns:
* N = Notes found in the "notes.dat" table.
* B = Summary line gives blue (Johnson U or B, blue photographic, etc.)
* magnitudes
* C = Orbit and Linear solution. A published orbit exists and this
* system has a Linear Solution as well. A "C" code, then,
* indicates both an "O" and an "L" code.
* D = Has measure in Delta-M catalog
* I = Identification uncertain. Match of object at precise position
* with WDS pair may or may not be correct. Currently under examination.
* K = Summary line gives K-band or other infrared (>1 micron) magnitudes
* L = Linear solution. Linear elements for this pair have been
* determined. Linear Elements Catalog is currently under development.
* M = Magnitude modified. Magnitudes have been corrected to the
* Tycho-V scale based on other systems measured by the
* discoverer and Tycho.
* O = Orbit, briefly described in WDSNOT MEMO and has entry in Orbit Catalog
* P = 100-year proper motion in right ascension and declination
* R = Summary line gives red (Johnson R or I, red photographic,
* etc.) magnitudes
* S = Statistically different parallax and proper motion indicates
* that this pair is non-physical.
* T = Statistically the same parallax within the errors and similar
* proper motion or other technique indicates that this pair
* is physical.
* U = Proper motion or other technique indicates that this pair
* is non-physical.
* V = Proper motion or other technique indicates that this pair
* is physical.
* X = A "Dubious Double" (or "Bogus Binary"). This pair may represent
* a positional typo in the original publication (so we're looking
* in the wrong location), an optical double disappearing due to
* radically different proper motions, a plate flaw, or simply a
* pair not at a magnitude, separation, etc., sufficiently similar
* to those noted when the first measure was added (making it too
* faint, too close, etc.).
* Y = Statistically different parallax for the components indicates
* they are non-physical.
* Z = Statistically the same parallax within the errors would
* indicate the components are physical.
* At present, column 108 is reserved for N, column 109 for O, L, C,
* or X and column 110 for D. The other codes can occur in any column.
*Note (5): Originally 3 letters represent the discoverer; an additional
* 'A' denotes an appendix, 'B' a second appendix, e.g. in the lists
* of F. Struve: STF1004 is the 1004th system in the main list,
* STFA 11 is the 11th system of the first appendix, STFB 12 is the
* 12th system of the second appendix, etc.
