Description:
This catalog contains databases of published photoelectric UBVbeta
data, MK-system spectral classifications, and Stroemgren four-color
uvby photometry for objects in the Stephenson-Sanduleak "Luminous
Stars in the Southern Milky Way" catalog (LSS catalog). The catalog
contains mostly OB stars and A and F supergiants. These databases have
been compiled from the literature.
