cds-question@unistra.frproper-motionsA new method for combined calculations of proper motions (PMs) based on accurate measurements of POSS1 and POSS2 epoch plates is given. The positional accuracy of various surveys and catalogues is estimated, and statistical weights for each of them are established. To achieve the best positions, weighted averaging of direct measurements on DSS1/DSS2, and data from APM, MAPS, USNO-A2.0, USNO-B1.0 and GSC 2.3.2 catalogues were used. The rms accuracy of positions achieved for POSS1 is 119mas in each coordinate and 168 mas total and for POSS2 is 69mas in each coordinate and 98mas total. Using these accurate positions and the large separation in years between POSS1 and POSS2, we have calculated the best possible proper motions: 3.9mas/yr in each coordinate and 5.5mas/yr total. We have worked out methods to control and exclude accidental errors that appear in any survey. We have compared and combined our PM with those given in USNO-B1.0, SDSS DR7, and Tycho-2 catalogs and obtained even better results: 3.0mas/yr in each coordinate and 4.2mas/yr total PM. This approach has been applied to the First Byurakan Survey blue stellar objects containing a significant number of white dwarfs and subdwarfs. Altogether 640 objects have been revealed with PM>=10mas/yr, the detection limit for this method; and an electronic table of these objects is given. For more confident proper motions, we adopt the limit 20mas/yr (333 objects). Adopting 50km/s as an upper limit for tangential velocities, we have calculated maximum distances and absolute magnitudes and estimated luminosity types for these objects and obtained 185 probable white dwarfs (M>8mag), 69 possible white dwarfs (6mag<M<8mag), and 42 candidate sd/WDs (3mag<M<6mag). Given that we have re-discovered 141 genuine white dwarfs among the classified objects, the success rate of discovery of white dwarfs is estimated as 83% and 38% for our probable and possible white dwarfs, respectively.2010MNRAS.407..681Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/407/681CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/267 : The APM-North Catalogue (McMahon+, 2000)I/252 : The USNO-A2.0 Catalogue (Monet+ 1998)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)II/223 : First Byurakan Survey (FBS), 2nd Program (Abrahamian+, 1990-96)J/A+A/426/367 : FBS blue stellar objects DSS1/DSS2 astrometry (Mickaelian 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/407/681https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/407/681http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/407/681https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/407/681https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/407/681http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/407/681GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/407/681/table2 (FBS blue stellar objects having {mu}>=10mas/yr)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/407/681/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/407/681/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/407/681/table2?GETtext/xml+votable180.050000true5.59661694440.4307819440.0055555555555555566/894 955-956 976 1002 1004 1009 1014 1019 1021 1570 1572 1668 1701 2039 2046 2236 2254 2257 2262-2263 2269 2281-2282 2297 2303 2316 2319-2320 2330 2332 2358 2399 2419 2424-2425 2444 2463 2477 2498 2572 2575 2577 2584-2585 2588 2591 2599 2606 2616 2621 2625-2626 2660 2664-2665 2670 2703 2714 2739 2756 2760 3082 3553 3566 3911 3928 4061 4082 5047 5068 5082 5109 5115 5118 5388 5393 5396 5399-5400 5406 5410 5420 5429 5434 5438-5439 5453 5463 5466 5470-5471 5481 5490-5492 5514 5521 5539 5544 5546 5550 5553 5569 5573 5643 5648-5650 5652 5655 5658 5682 5690 5698 5700 5710 5713 5720 5738 5746 5760-5761 5802 5809 5826-5827 5832-5833 5890 5893 6103 6108 6126 6129 6136-6138 6141-6142 6342 6365 6415 6425 6452 6461 6493 6503 6523 6540 6547 6579 6594 6676 6684-6685 6706 6710 6733 6737 6748 6754 6759 6808 6834 6848 6851 7157 7164 7171 7390 7403 7410 7412-7413 7415 7417 7423 7479 7483 7498-7499 7503 7510 7518 7520 7526 7531 7544 7555 7557 7559 7579 7582 7587 7596 7601 7606-7609 7614 7622-7623 7626 7631 7636 7639 7645 7655 7657 7663 7668 7670 7672 7719 7726 7734 7740 7750 7752 7755-7756 7765 7771 7777-7779 7795 7799 7808 7811 7818 7830 7836 7839 7848 7881 7883 7887 7894 7903 7908 7928 7946 7958 7971 7977 7982 8002 8004 8006 8044 8049-8050 8055 8063 8080 8082 8096 8108 8135 8139 8147 8152 8154 8160 8182 8190 9078 9083 9141 9165 9169 9176 9180 9186 9189 9202 9215 9424 9426 9429 9433 9454 9463 9484 9497 9501 9506 9510 9512 9516 9537 9539 9552 9554 9562 9567 9578 9585 9593 9602 9610 9614 9620 9633 9638 9640 9643 9651 9664 9747 9751 9762 9770 9775 9790 9793 9798 9800 9811-9812 9818-9820 9832 9839-9840 9842-9843 9859 9881 9886 9899 9901 9903 9907-9909 9993 10220 10226 10233 10357 10445 10458 10462 10471 10474 10489 10495 10519 10525-10526 10529 10536 10543 10552-10553 10584 10589 10593 10602 10604 10624 10629-10630 10637 10642-10645 10653 10655 10665 10671 10675 10677 10680 10759 10768-10769 10783-10784 10799 10802 10810 10815 10833 10854 10860 10863 10888 10890 10903 10905 10911 10923 10936-10937 10945 11016 11230 11245 11264 11479 11483 11486 11511 11514 11516 11518 11550 11576 11582 11593 11598 11605 11608 11612 11616 11636-11637 11642 11648 11650 11653 11678 11680 11684 11690 11694 11698 11704 11712 11721 11738 11746 11748 11768 11805 11823 11835 11844 11873 11875 11883-11884 11887 11902 11907 11918 11921 11929 11934-11935 11942 11944 11947 11951 11954 11957 11959 11970 11973 11984 11988 12022-12023 12048 12053 12062 12070 12083 12088 12092-12093 12100 12102 12104 12110 12114 12120 12135 12142 12156-12157 12163-12166 12172 12177 12192 12200 12204 12213 12222 12233-12234 12236 12238 12244 12252 12254 12284 13502 13521 13524 13534 13538 13542 13544 13555 13563-13564 13581-13582 13586 13589 13601 13613 13615 13623 13646 13651 13654 13659 13665 13668 13676 13681-13682 13688 13700-13701 13705 13707-13708 13718-13719 13732-13733 13745 13748 13752 13754 13760 13768 13770 13840 13853 13855 13888 13896 13922 13931 13944 14089 14890 14939 14961 14984 14986 14991 15002 15015 15021 15023 16046 16296 16303 16316 16378 20343 20351 20411 20423 20472 28543 28615 28622 28637-28638 28646 28663 28666 32719 32731 32733 32746 32762https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/407/681?format=asciiOpticaldefaultJ/MNRAS/407/681/table2FBS blue stellar objects having {mu}>=10mas/yrrecnoRecord number assigned by the VizieR team.
