Galactic O Stars with Accurate Spectral Classes Catalog

The authors have produced a catalog of 378 Galactic O stars (the GOS Catalog) 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. There is also a web-based version of this catalog with links to online services at <a href="http://www-int.stsci.edu/~jmaiz/research/GOS/GOSmain.html">http://www-int.stsci.edu/~jmaiz/research/GOS/GOSmain.html</a> This table was created by the HEASARC in February 2009 based on the electronic versions of Tables 1, 2, 5, 6, 8, 9, 10, 11, 12 and 13 obtained from the CDS, namely their catalog V/116 (files main.dat, posplx.dat, tyc2mmag.dat, ubvmag.dat and dist.dat). This is a service provided by NASA HEASARC .
