Conversion of standardized ReadMe file for
file /./ftp/cats/III/264 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): "Cat" is BD for the first part (except "3586" at line 546 which
* represents the GSC field number for star originally named "+51 2938")
* and "[V39]" for the second part (non-BD stars)
*Note (2): Source is as follows:
* M = 2MASS (Cat. II/246)
* T = Tycho-2 (Cat. I/259)
* U = UCAC3 (Cat. I/315)
* * = star not found; the position is then the original position
* precessed to J2000, and the magnitude the original
* photographic magnitude.
*Note (3): the spectral types are formally on the 'Uppsala' system, which
* includes using the strength of the CN band to distinguish dwarfs and
* giants among types later than G5. These were converted into MK
* equivalents, see details in the "Description" section above.
