By comparison with other major surveys such as the ROSAT All Sky Survey (Cat. <IX/10>, the ROSAT WGACAT (Cat. <IX/12>) catalogue of point sources, the IRAS (Cat. <II/125>) survey, the 6cm Green Bank (Cat. <VIII/52>, the 1.4GHz NRAO VLA (Cat. <J/AJ/115/1693>, and the 92cm Westerbork Northern sky surveys (Cat. <VIII/62>) and with the catalogue of mean UBV data on stars, we estimate the number of AGNs present in the FBS survey and its completeness. We have made spectroscopic observations of nine of the most promising FBS candidates. We have found six new QSOs, bringing the total number of known QSOs in this survey to 42. By comparison with the Bright Quasar Survey, we found that the completeness of this last survey is of the order of 70% rather than 30-50% as suggested by several authors.1999Ap.....42....1Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Ap/42.1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/223 : First Byurakan Survey (FBS), 2nd Program (Abrahamian+, 1990-1996)III/258 : Revised and updated First Byurakan Survey (FBS) (Mickaelian, 2008)VII/172 : First Byurakan Survey (FBS) (Markarian+, 1989)J/other/Ap/41.356 : FBS red stars (Gigoyan+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Ap/42.1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Ap/42.1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Ap/42.1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Ap/42.1https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Ap/42.1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Ap/42.1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Ap/42.1/table1 (Accurate positions for 195 FBS objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Ap/42.1/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Ap/42.1/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Ap/42.1/table1?GETtext/xml+votable180.050000true1.885562233.29192350.0055555555555555566/976 1011 1701 2277 2297 2303 2328 2358 2371 2425 2439 2444 2463 2477 2575 2584 2665 2674 2703 2717 2753 2760 3566 3909 3911 5084 5409 5434 5438 5458 5463 5481 5490 5492 5521 5553 5652 5682 5691 5700 5746 5760 5789 5832 5893 6136 6142 6267 6380 6391 6425 6493 6594 6684 6713 6733 6814 6834 7404 7415 7417 7511 7536 7552 7567 7576 7582 7587 7596 7601 7602 7606 7614 7631 7636 7670 7752 7771 7778 7808 7845 7893 7908 7933 7964 7981 8055 8077 8108 8114 8137 8155 8160 9433 9436 9461 9497 9506 9512 9526 9533 9561 9567 9587 9602 9610 9614 9633 9651 9664 9751 9764 9770 9786 9794 9806 9826 9839 9843 9901 10462 10519 10572 10589 10629 10630 10642 10653 10677 10782 10799 10860 10873 10890 10905 10926 11014 11016 11231 11514 11515 11576 11582 11605 11678 11683 11690 11723 11829 11882 11920 11926 11942 11959 12002 12053 12083 12088 12092 12102 12165 12213 12222 12280 13659 13708 13719 13726 13733 13754 13768 13915 13923 13931 14890 14984 15002 15042 15049 15351 16046 16314 20351 20423 28618 28666 32719 32733 32764https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Ap/42.1?format=asciiOpticaldefaultJ/other/Ap/42.1/table1Accurate positions for 195 FBS objectsrecnoRecord number assigned by the VizieR team.
