cds-question@unistra.frsurveysinfrared-sourcesdwarf-starsproper-motionsThe UK Infrared Telescope Infrared Deep Sky Survey (UKIDSS) is the first of a new generation of infrared surveys. Here, we combine the data from two UKIDSS components, the Large Area Survey (LAS) and the Galactic Cluster Survey (GCS), with Two-Micron All-Sky Survey (2MASS) data to produce an infrared proper motion survey for low-mass stars and brown dwarfs. In total, we detect 267 low-mass stars and brown dwarfs with significant proper motions. We recover all 10 known single L dwarfs and the one known T dwarf above the 2MASS detection limit in our LAS survey area and identify eight additional new candidate L dwarfs. We also find one new candidate L dwarf in our GCS sample. Our sample also contains objects from 11 potential common proper motion binaries. Finally, we test our proper motions and find that while the LAS objects have proper motions consistent with absolute proper motions, the GCS stars may have proper motions which are significantly underestimated. This is possibly due to the bulk motion of some of the local astrometric reference stars used in the proper motion determination.2009MNRAS.394..857Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/394/857CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/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=J/MNRAS/394/857https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/394/857http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/394/857https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/394/857https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/394/857http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/394/857GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/394/857/UCstars (Ultracool dwarf stars resulting from the)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/394/857/UCstars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/394/857/UCstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/394/857/UCstars?GETtext/xml+votable180.050000true0.25887515.76441670.0055555555555555566/44 369 457-458 462 466 468 472 478 487 496 544 548-549 1066 1086 1128 1130-1131 1160 1164 1166 1536 1540 1544 1549 1769 3095 3136 3144 4125 4127 4136 4142 4145 4163 4183 4187 4194 4206 4226 4251 4261 4355 4687 4703 4705 4711 4721-4722 4729 8250 8260 8263 8265 8270 8274 8277-8278 8281-8282 8289 8292 8295 8298-8299 8304 8314 8330 8335 8342 8348-8350 8354 8374-8375 8381-8382 8386 8449 8715 17406 17745 17757 17767 17814 17816 17819 17856 17883 17906 18019 18025 18067 18252 18303 18381 18772-18773 18782 18788 18790 18802 18839 18846 18853 18856 18931 19007 19023 19030 19034 19038 19047 19050 19280 19457-19458 19618 19686-19687 19697 19726 19733 19755 19776 19981 19983 20035 20040 21438 21839 21861-21862 21881 21978 22001 22004-22005 22805 22848 22850 22852 23103 23181 23193 23211 23234 26020 26101 26109 26267 26333 26339 26346 26350 26355 26357 26364 26428 26447-26449 26468 26483 26488 26490 26506 26509 26517-26519 26521-26522 26552-26553 26561 26563 26567 26966 26969-26970 26979 26981-26982 27188 27208 27232 27236 27277 27281 27283 27291 27301 27308 27373 27377 27386 27392 27525 27535 27554 27561 27572 27666-27667 27699 27702 27728 27730 27739-27740 27746 27761 27767-27768 27773 27910 27938 27952 31292 31370 31423 31437 31469 31471 31474 31479 31782 40953 42909 42963 42969 42983 42992 42997 43003-43004 44342 45023 45046https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/394/857?format=asciiInfrareddefaultJ/MNRAS/394/857/UCstarsUltracool dwarf stars resulting from therecnoRecord number assigned by the VizieR team.
