It covers 17,000 sq.deg. in the Northern sky together with a high galactic latitudes region in the Southern sky. This service serves the scanned objective prism images and offers SODA-based cutouts.2007A&A...464.1177Mhttp://dc.g-vo.org/tableinfo/dfbsplates.mainArchiveResearchIsServedByGAVO Data Center ObscoreByurakan Astrophysical Observatory BAOByurakan 1m Schmidt0/1-2 1/0,17-19,22,25-27 2/6,8-10,15,48-49,52-54,58-59,67,85,99,117,120,122-123,126-127,141,143,159,175,191 3/18,21,23,29,31,44-46,48-50,53-55,200-201,205,220-221,227,230,250-251,253-255,261-263,265-267,330-331,334,348-349,351,370,373,375-376,381,383,391,395,465,486,498-499,502-503,542-543,569-571,630-631,635,695,699,757-759,761,76340383 44374OpticalivoaDefinition and support code for the ObsCore data model and table.ivoa.obscoreThis data collection is queryable in GAVO Data Center's obscore table.dfbsplates The First Byurakan Survey (FBS) is the largest and the first systematic objective prism survey of the extragalactic sky.
