cds-question@unistra.frproper-motionsThe completeness of USNO-B detections of high proper motion ({mu}>180mas/yr) stars is tested, and the accuracy of its measurements is compared to the revised New Luyten Two-Tenths catalog of Salim & Gould (2002ApJ...575L..83S). For 14.5<V<18.5, only 6% of such stars are missing from USNO-B (Cat. <I/284>), while another 3% have large errors, mostly too large to be useful. Including both classes, incompleteness is 9%. These fractions rise toward both brighter and fainter magnitudes. Incompleteness rises with proper motion to 30% at {mu}=1"/yr. It also rises to 35% at the Galactic plane, although this is only determined for relatively bright stars V<~14. For binaries, incompleteness rises from 9% at separations of 30" to 47% at 10". The proper-motion errors reported internally by USNO-B are generally correct. However, there is a value of {sigma}{mu}~4mas/yr below which the reported errors should not be taken at face value. The small number of stars with relatively large reported errors ({sigma}{mu}>~20mas/yr) may actually have still larger errors than tabulated.2003AJ....126..472Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/472CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/98 : NLTT Catalogue (Luyten, 1979)J/ApJ/582/1011 : Revised NLTT Catalog (Salim+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/472https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/472http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/472https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/472https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/472http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/472GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/126/472/table1 (Binary Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/472/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/472/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/472/table1?GETtext/xml+votable180.050000true0.63623-8.438330.0055555555555555566/396 401 404 413 447 542 569 612 636 682 709 758 776 784 807 815 974 991-992 998 1029 1073 1075 1077 1089 1407 1483 1510 1521 1678-1679 1692 1694 1860 1876 2070 2169 2268 2298 2331 2390 2402 2421 2446 2496 2640 2646 2654 2695 2736 2754 2761 2793 2850 2894 2958 2978 3100 3865 3870 4402 4469 4559 4591 4633 4708 4714 4800 4933 4936 5028 5186 5207 5225 5230 5242 5250 5254 5325 5350 5447 5455 5466 5483 5532 5534 5540 5544 5695 5741 5743 5828 5838 5921 5923 5972 6105 6180 6421 6454 6492 6517 6565 6576 6662 6752 6923 7211 7376 7504-7506 7606 7772 7828 7854 7900 7978 8013 8022 8025 8054 8079 8088 8093 8102 8168 8446 8482 8509 8592 8607 8765 8873 8897 8908 8917 8922 8939 9178 9272 9374 9383 9453 9466 9737 9746 9764 9772 9785 9920 9954 9960 9999 10025 10099 10141 10169 10223 10243 10245 10248 10343 10349 10355 10397 10408 10428-10429 10433 10440 10462 10581 10638 10726 10745 10787 10856 10886 10891 10896 10900 10926 10964 10984 11019 11172 11177 11212 11217 11238 11248 11374 11385 11546 11629 11667 11799 11819 11838 11847 11863 11914 11975 12025 12136 12507 12601 12705-12707 12716 12856 12919 12925 13158 13360 13388 13769 13853 13998 14576 14603 15012 15036 15052 15379 15885 16118 16455 16463 16478-16479 16483 16503 16536 16578 16597 16619 16688 16699 16722 16733 16821 16832 16897 16907 16955 16969 16994 17017 17139 17161 17195 17202 17222 17229 17234 17241 17256 17277 17288 17309 17322 17341 17345 17399 17420 17487 17537 17551 17579 17595 17613 17642 17658-17659 17812 17825 17928 17935 17946 17966 17968 17983 18003 18005 18024 18049 18064 18358 18377 18394 18538 18548 18615 18683 18765 18818 18822 18973 19107 19321 19385 19414 19441 19751 19873 19879 19887 19975 20000 20005 20123 20127 20196 20239 20289 20332 20334 20355 20363-20364 20395-20396 20438 20948 20993 21036 21145 21249 21378 21773 21777 21806 21826 22459 22525 22563 22585 22591 22714 23079 23106 23493 23737-23739 23755 23902 23939 24093 24159 24792 24838 24945 24968 24995 25034 25083 25093 25117 25165 25252 25280-25281 25283 25296 25466 25552 25635 25672 25780 25809 25827 25848-25849 25851 25897 25903 26005 26138 26143 26169 26192 26556 26565 26634 26656 26690 26706 26768 26792 26794-26795 26824 26864 26916 26927 26956 27143-27144 27179 27225 27511 27714 27765 27767 27772 27838 27858 27872 27911 27930 27932 27939 27944 27984 28074 28083 28097 28099 28101 28171 28271 28279 28357 28408 28420 28459-28460 28463 28569 28616 28620 29021 29284 29348 29419 29484 30023 30033 30346 30848-30849 31717 31720 32089 32317 32599 32602 34301 34637 34656 34660 34682 34684 34713 34749 34757 34786 35325 35327 35670 35675 35679 35717 35727 35730 35735 35782 35786 35919-35920 35923 35945 35950 35962 36016 36074 36139 36142 36152 36177 36284 36322 36353 36368 36383 36403 36456 36483 36510 36512 36522 36525 36541 36566 36617 36625 36629 36644 36651 36657 36660 36711 36729 36773 40260 40283 40381 40412 40480 40505 40540 40623 40740-40741 40788 40820 40831 40934 43893 44025 44115 44123 44197 44201 44215 44257 44399 44609 44613 44681 44751 44846 46927 46939 46962 47981 48234 48237 48285 48413 48439 48478 48497 48499 48564 48680 48713 48784 48787 49125 49132https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/472?format=asciiOpticaldefaultJ/AJ/126/472/table1Binary SamplerecnoRecord number assigned by the VizieR team.
