Description: (Excerpt from the "intro.txt" file)
Between 1959 and 1971, the Hamburg and Warner and Swasey Observatories
published a seven-volume survey listing intrinsically luminous stars
(hereafter "LS" objects) - mostly OB stars, as well as a number of A,
F, and G supergiants and Wolf-Rayet stars - within about ten degrees
of the plane of the Milky Way to a limiting photographic magnitude of
approximately 13.5. Based on objective-prism surveys of dispersion 580
Angstrom per millimeter at Hydrogen-gamma, these catalogs have served
as starting points for numerous investigations of galactic structure
and the characteristics of massive stars.
Much fundamental data on the LS stars now exists distributed
throughout the astronomical literature. This work describes a
compilation of published photoelectric UBV-Beta photometry and
spectral classifications nominally on the MK system for the LS stars,
as well as an extensive cross-identification table linking LS numbers
and other commonly-used identifiers such as HD, BD, CD, CPD and HR
numbers. At this writing, the UBV-Beta portion of the database covers
both the Northern and Southern LS stars, whereas MK classifications
have as yet only been fully compiled for the Southern stars;
compilation of MK types for the Northern LS stars is as yet
incomplete, but ongoing.

Note on Alma-LS: this number is the LSS (Luminous Southern Stars)
when less than 6000 (the volume number is then zero),
and starts from 6001 in Northern Milky Way.
Note on LS: the volume number as a roman numeral is in bytes 9-11,
the declination zone in bytes 13-15,
and the running number in bytes 17-20.
This field is blank for Southern stars (i.e. Alma-LS < 6000)
