Abstract:
We have produced a catalog of 378 Galactic O stars with accurate
spectral classifications that is complete for V<8 but includes many
fainter stars. The catalog provides cross-identifications with other
sources; coordinates (obtained in most cases from Tycho-2 data);
astrometric distances for 24 of the nearest stars; optical (Tycho-2,
Johnson, and Stroemgren) and NIR photometry; group membership, runaway
character, and multiplicity information; and a Web-based version with
links to on-line services.

Note (3): Uncertain determinations are indicated by a colon.
Note (4): Based on the following recipe.
1] Stars listed as runaways in Hoogerwerf et al., 2001A&A...365...49H 2001A&A...365...49H
or Mason et al., 1998AJ....115..821M 1998AJ....115..821M, have a "yes"
2] Other stars in clusters/associations or stars in Mason et al.,
1998AJ....115..821M 1998AJ....115..821M, not listed as runaways have a "no".
3] Other stars with "Field:"' in the previous column have a "no:".

Global notes:
Note (G1): Produced according to the criteria recommended by the IAU
Lortet et al. (1994A&AS..107..193L 1994A&AS..107..193L). The first character is always a G
(indicates Galactic coordinates), the next six express the Galactic
longitude in degrees in the format LLL.ll, the eighth character is the
latitude sign, the next five express the absolute value of the
Galactic latitude in degrees in the format BB.bb, the fourteenth is an
underscore, and the fifteenth and sixteenth are a running number to
differentiate stars which would otherwise have the same catalog
number. Note that a previous web-based version of this catalog used a
different nomenclature with arcminutes instead of decimal degrees.
