Abstract:
Hβ photometry is given for 263 reddened and very reddened stars
from the Stephenson & Sanduleak (1971, Cat. III/43) catalogue of
Luminous Stars in the Southern Milky Way (LSS). The results are
combined with the uvby photometry presented in Paper I to determine
reddenings, E(b-y), and distances for the stars and to estimate the
spectral types and luminosity classes from derived Teff and MV
values.
