Description:
A database of published Stroemgren four-color uvby photoelectric
photometry f or objects in the Stephenson-Sanduleak Luminous Stars in
the Southern Milky Way catalog has been compiled from the literature.
Of 5132 stars in the catalog, 817 have uvby colors and magnitudes
available; altogether, the database incorporates 1181 observations
from 41 references. The database is available electronically at CDS,
and lists LS number, HD or CD number, b-y, m1, c1, number of
observations, numeric codes for notes and references, galactic l and b
coordinates, and aliases for named or variable stars.

Note (1): Remarks on Individual Stars
[98] Variations in the spectrum of this Wolf-Rayet star are discussed
by Wilson (1948PASP...60..383W 1948PASP...60..383W) and a flux-calibrated spectrum of
this star to the Lyman limit is discussed in Mccandliss, et. al.
(1993ApJ...416..372M 1993ApJ...416..372M). Howarth and Schmutz (1995A&A...294..529H 1995A&A...294..529H)
report a distance of 1.8 kpc for this star.
[166] Gies, et. al. (1994ApJ...422..823G 1994ApJ...422..823G) remark that this star is a
spectroscopic binary with a period of 6.0173 days. The companion
has a mass ratio 0.23 + 0.04, and a magnitude difference 3.3 + 0.4.
[949] Reported as variable by Balona (1992MNRAS.254..404B 1992MNRAS.254..404B)
[1657] See notes in Paper I.
[1673] In NGC 3293. Stephenson and Sanduleak indicate this star as number
21 in the finding chart of Feast (1958MNRAS.118..618F 1958MNRAS.118..618F). However,
references 30 and 31 in Paper I both indicate that this star is an
M1 supergiant with B-V=2.0. When precessed to 1875, the
coordinates of LS 1673 match very closely to those of
CPD=-57 3506, a B1 II star which is number 22 in Feast's chart.
I have assumed that Stephenson and Sanduleak marked the wrong star;
the data given is that for Feast's number 22.
[1679] See notes in Paper I.
[1688] See notes in Paper I.
[1689] HD 92025. Misidentified in the LS catalog as HD 92007
[2212] As LS 949.
[2803] uvby colors given by Crawford, Barnes, and Golson (1971a; reference 3
in Table 1) for HR 4890 (= LS 2813) correspond to those of
LS 2803 according to other sources; their data have been attributed
to LS 2803 = HR 4887. In NGC 4755.
