Abstract:
Stroemgren uvby photometry has been obtained for 270 reddened and very
reddened OB stars selected from the Stephenson & Sanduleak (1971)
catalogue of Luminous Stars in the Southern Milky Way (LSS), Cat.
III/43. Corrections have been applied to convert the data as closely
as possible to the reddened O stars observed by Crawford
(1975PASP...87..481C 1975PASP...87..481C). Uncorrected and corrected data ar presented in
Tables 1 and 3, respectively.

Notes (1): a: Large std. dev. in table1; variable or probable variable
b: Large difference between V from uvby and from VRI (paper III)
(Kilkenny et al., 1993SAAOC..15...65K 1993SAAOC..15...65K) even after allowance for
reddening effects on magnitudes; probably variable
c: Large difference between V from uvby and V from Drilling
(1991ApJS...76.1033D 1991ApJS...76.1033D) even after allowance for reddening effects
on magnitudes; probably variable
d: Drilling (1991ApJS...76.1033D 1991ApJS...76.1033D) lists as probable variable:
V flagged with ':'
f: Eclipsing binary (Kilkenny et al. 1991IBVS.3659....1K 1991IBVS.3659....1K)
g: Ectipsing binary (Kilkenny al. 1992IBVS.3801....1K 1992IBVS.3801....1K)
h: Faint star(s) nearby; excluded from aperture
i: Faint star(s) nearby included in aperture
J: obvious nebulosity on photographic plates; variable
background could effect photometry
k: Weak nebulosity on photographic plates
