cds-question@unistra.frinfrared-sourcesinfrared-photometrysurveysA special set of observations that utilized exposure times six times longer than the main 2MASS survey measurements were conducted in the final year of 2MASS observatory operations. The 2MASS "6x" observations achieved sensitivities ~1 mag deeper than the main 2MASS survey, and covered approximately 590 deg2 of sky in 30 discrete regions. The 2MASS 6x Point Source Working Databases (6x-PSWDB and 6x-XSWDB) contain all detections extracted from the raw 6x imaging data during pipeline data reduction. The 6x WDB entries include reliable detections of astrophysical sources, as well as spurious detections of noise excursions, image artifacts and transient events such as meteor trails, cosmic rays and hot pixels. In addition, the WDBs may contain multiple, independent detections of objects scanned more than once during the 6x observations. The 2MASS 6x Point Source Catalogs (6x-PSC and 6x-XSC) is a subset of extractions in the 6x-PSWDB that have been identified to be high reliability source detections, with only one measurement of sources detected multiple times for uniformity.2012yCat.2281....0Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/281CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://http://www.ipac.caltech.edu/2mass/releases/allsky/doc/explsup.html :II/246 : The Two Micron All-Sky Survey: Point sources (Cutri+ 2003)VII/233 : The Two Micron All-Sky Survey: Extended sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/281https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/281http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/281https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/281https://vizier.iucaa.in/viz-bin/votable?-source=II/281http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/281GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/281/2mass6x (2MASS-6X)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/281/2mass6x?https://vizier.iucaa.in/viz-bin/conesearch/II/281/2mass6x?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/281/2mass6x?GETtext/xml+votable180.050000true45.45598312.9904840.005555555555555556Hips catalogue for table II/281/2mass6xhttps://hipscat.cds.unistra.fr/HiPSCatService/II/281/2mass6x3/516-517 520 4/379 2076 2088 2112 2336 2338 2344 2346-2347 2432 5/115 118 425 557 655 1509-1511 1528 3869 8215 8220-8221 8223 8235-8236 8238 8289 8292-8293 8295 8308-8310 8312-8313 8344 8346 8356-8358 8360-8362 8452-8454 8456-8458 9259 9350 9356 9358 9380 9382-9383 9677 9691 9713 9716 9732-9734 9736-9738 10283 6/205 207 455 466 484-485 496 859-860 862-863 881 884 975 984 986-987 997 1008 1455 1466 1537-1540 1542 1544-1545 1548 1678-1679 1690 1712 1797 1799 1808 1810 2225 2227 2233 2236 2261 2346-2347 2401-2404 2406 2408-2409 2412 2432-2434 2619 2666 2705 2708-2709 2752 4718-4719 4801 4804-4806 5951 5994 6031 6035 6053 6080 6082 6088 6090 6120-6122 6883 6886-6887 6889 6892-6893 7441 7443-7446 14829-14831 14840 14842 15172-15173 15484 16889 16891 16894 17236-17237 17239 17478-17479 17485 17496 17498-17499 17521 17524 17526-17527 17533 17922 17928-17929 17931 17934 17936-17937 17939 17942 17948-17949 17951 17994 18016-18017 18019 18022 18028 32853-32855 32857-32859 32869-32871 32888-32889 32922-32923 32933-32935 32937-32939 32950 32956 32958-32959 33152-33153 33176-33177 33179 33201 33204-33205 33207 33244 33257 33260 33264 33346 33352 33354-33355 33388 33436 33452 33456 33472 33820 33836 33840 33856 33920 34816 37029-37031 37033-37035 37042 37048 37050 37100 37102-37103 37392 37394-37395 37436 37438 37445 37447 37456 37458 37464-37465 37467 37524 37526 37608 37610 38685-38687 38705 38707 38716-38717 38730 38752 38754-38755 38760 38763 38778 38849 38851 38860-38861 38872 38940 38956 38960 38976 39040 39279 39365 39376 39378-39379 39385 39388 39390-39391 40018-40019 40022 40024-40025 40027-40028 40030 40225-40227 40230 40232-40233 40235-40236 40238 40723 40726 40728-40729 40731-40732 40803 40808-40809 40811-40812 40814 41003 41006 41089 41091-41092 41125-41127 41144 41146 41476-41477 42610-42611 42614-42615 42617 42620-42621 42959 42980-42981 42983 42992 42994 43791 43813 43815 43824 43826-43827 43832-43833 43835-43836 43838-43839 43924-43925 43968 45312-45313 45316-45317 45328-45329 45332-45333 45376-45377 45380-45381 45392-45393 45396-45397 460808.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/281?format=asciiInfrareddefaultII/281/2mass6x2MASS-6X2MASSSource designationmeta.id;meta.maincharprimaryRAJ2000Right ascension (J2000)degpos.eq.ra;meta.mainDEJ2000Declination (J2000)degpos.eq.dec;meta.maineeMajSemi-major axis of the error ellipsearcsecphys.angSize.smajAxis;pos.errorEllipsefloateeMinSemi-minor axis of the error ellipsearcsecphys.angSize.sminAxis;pos.errorEllipsefloateerPAPosition angle of the error ellipsedegpos.posAng;pos.errorEllipsefloatJmag?
