cds-question@unistra.frsurveysastrometryproper-motionsThe UCAC2 is the second release of the ongoing UCAC project, designed to observe the entire sky for R magnitudes of about 7.5 to 16. The observed positional errors are about 20 mas for the stars in the 10-14 magnitude range, and about 70 mas at the limiting magnitude of R~16. For up-to-date information on the project, see the UCAC web page at http://ad.usno.navy.mil/ucac/ . This web page will also serve as the location that the UCAC team will post addenda to the UCAC2 catalog. The UCAC2 is a high density, highly accurate, astrometric catalog of 48,330,571 stars covering the sky from -90 to +40 degrees in declination and going up to +52 degrees in some areas. The northern limit is a function of right ascension. Proper motions and photometry are provided for all stars. Positions and proper motions are on the ICRS (International Celestial Reference System) and given at the epoch J2000.0. The UCAC2 has a number of major differences with respect to UCAC1. These differences include: - much larger sky coverage - reduced systematic errors of CCD observations - positions given at a standard epoch (J2000.0) - the addition of several new catalogs for improved proper motions - photometry in the J, H, and K_s bands from the 2MASS project Additional details of the data are found in Sections 3, 4, and 5 of the "readme.txt" file. UCAC2 is the last intermediate data release before the final, all sky catalog will be constructed. Observations will end around mid 2004; the final catalog is expected out in 2005. The UCAC project, observations, and first data release are described in detail in the paper Zacharias et al. AJ 120, 2131 (2000). Versions of that and other related papers are placed on the UCAC Web page (http://ad.usno.navy.mil/ucac/). The paper describing UCAC2 is in preparation (AJ, 2003); some further details can be found in the "readme.txt" file. Notice: The data are freely available; however, any publication utilizing these data should make proper reference to the project and papers.2004AJ....127.3043Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/289CatalogResearchIsServedByTAP VizieR generic serviceIsPreviousVersionOfI/315IsServedByConesearch servicerelated-tohttp://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/ucac : UCAC Home PageI/268 : UCAC1 Catalogue (Zacharias+ 2000)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/289https://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/289http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/289https://vizier.cds.unistra.fr/viz-bin/votable?-source=I/289https://vizier.iucaa.in/viz-bin/votable?-source=I/289http://vizieridia.saao.ac.za/viz-bin/votable?-source=I/289GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/289/out (output)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/289/out?https://vizier.iucaa.in/viz-bin/conesearch/I/289/out?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/289/out?GETtext/xml+votable180.050000true124.1201789-89.98389090.0055555555555555560/4-11 1/0 4 8 12 2/4 8-9 20 24 36 40 52 56 3/20-22 24-26 40-42 44 48 84-86 88-90 100-102 104-106 148 152-154 164-166 168-170 212-214 216-217 228 232 4/92 94 108-110 112-114 172-174 180 184 200 348 350 364 368-370 412 428 432 448 596 600-602 620 668-669 684 688 704-706 860-862 872-874 876 880-881 916-918 920 932 936 5/372-374 444 446 460 464 480 700-702 724 728 740 744 784-786 788 804 808 1396 1398 1460-1462 1464-1465 1484 1488 1652 1656 1716 1720-1722 1732 1736 1796 1800 2388 2392-2394 2412 2484 2486 2488-2490 2496-2498 2504 2680-2682 2740-2742 2744 2756-2758 2760-2762 2828 2832 2848 3452-3454 3500-3502 3508-3510 3512 3528-3530 3532 3536-3537 3676 3684-3686 3688-3690 3696 3732 3734 3736 3748 3752 3840-3842 6/1500-1502 1520-1522 1780-1782 1788 1844 1848-1850 1860 1864 1924 1928 2812-2814 2900 2904 2916 2920 2964 2968 2980 2984 3148-3150 3168-3170 3176 3220 3224 3236 3240 5588-5590 5616-5617 5852-5854 5864-5866 5872 5940 5944 5956 5960 6016-6018 6612-6614 6616 6628 6632 6868-6870 6872-6874 6896 6932 6936 6948 6950 6952-6954 7188-7190 7192-7194 7204-7206 7208 7210 9556 9560 9562 9580 9652 9654 9656-9658 9664 9940-9942 9948 9964 9966 9968 9996 9998 10000 10024-10026 10732-10734 10736-10738 10740 10972 10974 10980-10982 10984-10986 11036-11038 11052-11054 11056-11058 11072-11074 11136-11138 11316 11320-11322 11336 11396-11398 11400-11401 13820-13822 14012-14014 14044 14052-14054 14056 14124-14125 14132 14134 14136 14152-14154 14156 14160-14161 14208 14708-14710 14712 14748-14750 14764-14765 14768-14770 14932-14934 14940 14948-14950 14952-14953 14996 15000 15012 15016 15104 15372 15376-15378 153928.650015785639275e-20 3.4272990383579255e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/I/289?format=asciidefaultI/289/outoutputphf2MASS photometric quality flag (9)meta.code.qual;photintccf2MASS confusion flag (10)meta.codeint2UCAC[00000001,48330571] UCAC designation (1)meta.id;meta.mainintprimaryRAJ2000Right ascension (degrees), J2000, Ep=J2000 (2)degpos.eq.ra;meta.mainEpRACentral epoch for mean RA (3)yrtime.epochdoubleEpDECentral epoch for mean Declination (3)yrtime.epochdoublepmRAProper motion in RA(*cos(Dec)) (7)mas/yrpos.pm;pos.eq.rafloate_pmRAMean error on pmRA (8)mas/yrstat.error;pos.pm;pos.eq.rafloatpmDEProper motion in Decmas/yrpos.pm;pos.eq.decfloate_pmDEMean error on pmDE (8)mas/yrstat.error;pos.pm;pos.eq.decfloatqpmRAGoodness of fit for pmRA (8)stat.fit.goodnessfloatqpmDEGoodness of fit for pmDE (8)stat.fit.goodnessfloat2Mkey2MASS (II/246) Unique source identifiermeta.id.crossJmag?
