Beginning of ReadMe : VII/276 Second Byurakan Survey. General Catalogue (Stepanian, 2005) ================================================================================ The Second Byurakan Survey. General Catalogue. Stepanian J.A. <Rev. Mex. Astron. Astrofis., 41, 155-368 (2005)> =2005RMxAA..41..155S =2016yCat.7276....0S ================================================================================ ADC_Keywords: Surveys ; QSOs ; Galaxies, photometry ; Redshifts ; Morphology ; Photometry, photographic ; Photometry, infrared Keywords: galaxies: active - galaxies: fundamental parameters - galaxies: Markarian - galaxies: Seyfert Abstract: The Second Byurakan Survey (SBS) General Catalogue is presented. The SBS, a continuation of the Markarian survey reaching fainter limiting magnitudes, is the first survey which combines the search of galaxies and QSOs. A total area of 991 square degrees of the Northern sky was covered with the use of three objective prisms in combination with Schott filters. The limited magnitude on the best plates reached B 19.5. The General Catalogue consists of 3563 objects presented in two parts: a Catalogue of galaxies (1863 objects) and one of stellar objects (1700 objects). The Catalogue of SBS AGN consists of 761 objects (155 SyG, 596 QSOs, and 10 BLLac). Multi-wavelength data are presented for 1438 SBS objects identified with X-ray, IRAS and FIRST sources. Spectrophotometric observations obtained over 26 years are available for 3132 objects. Redshifts were measured for  2100 extragalactic objects. Spectral classification is presented for  2970 objects. The majority of the data is presented here for the first time. The Catalogue presents new large homogeneous deep representative complete samples of bright QSOs, AGNs, and faint UVX galaxies in the Northern sky. The SBS sample is found to be complete at 70% for galaxies and  85% for AGN/QSOs with B<=17.5. Description: The Second Byurakan Survey is a continuation of the Markarian survey, which aimed to reach fainter limiting magnitudes. The investigation of fainter objects, in particular QSOs, required the extension of the survey to these fainter magnitudes. The SBS survey is in fact the first simultaneous and combined survey of galaxies and quasars. The SBS objective-prism observations started in 1974 and finished in 1986. Plate searching was completed in 1991. Between 1974 and 1986 a total area of 991 square degrees of the Northern sky was observed. This area is confined to the strip defined by 7:40 < alpha <17:15 in right ascension and +49:00 < delta < +61:00 in declination.
