Description
Eleven lists of blue stellar objects (BSOs) found in the First Byurakan Survey (FBS) low-dispersion spectroscopic plates were published in the journal Astrophysics in the period 1990-1996, The selection was carried out in the region with declinations +33 deg. < delta < +45 deg. and delta > +61 degrees with a surface area of 4000 square degrees. As a result, the present catalog of the FBS blue stellar objects (BSOs) has been compiled. Its preliminary version has been available at CDS since 1999. The author has revised and updated the FBS BSOs catalog with the new data from recently published optical and multi-wavelength catalogs to give access to all available data and make further comparative studies of the properties of these objects possible. The author has made cross-correlations of the FBS BSOs catalog with the MAPS , USNO-B1.0, SDSS, and 2MASS catalogs, as well as with ROSAT, IRAS, NVSS, and FIRST catalogs , added updated SIMBAD and NED data for the objects, and provided accurate DSS1 and DSS2 positions and revised photometry. The author also checked the objects for proper motion and variability. A refined classification for the low-dispersion spectra in the Digitized First Byurakan Survey (DFBS) was carried out. The revised and updated catalog of 1103 FBS blue stellar objects is presented here. (The catalog in fact contains 1101 objects, as 2 pairs of objects turned to be identical; however, the author has kept all objects in the list on order to allow users to enter and find objects by all accepted FBS names). The FBS blue stellar objects catalog can be used to study a complete sample of white dwarfs, hot sub-dwarfs, horizontal-branch B (HBB) stars, cataclysmic variables, bright AGN, and to investigate individual interesting objects. This table was created by the HEASARC in October 2008 based on the CDS table III/258 file fbs.dat. This latter catalog supersedes the previous edition (Abrahamian et al. 1999, <a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/223">CDS Cat. II/223</a>) This is a service provided by NASA HEASARC .
