cds-question@unistra.frmultiple-starsyoung-stellar-objectsinfrared-photometryWe present the observational results of a near-infrared survey of a large sample of Class I protostars designed to determine the Class I binary separation distribution from ~100AU to ~5000AU. We have selected targets from a new sample of 267 nearby candidate Class I objects. This sample is well understood, consists of mostly Class I young stellar objects (YSOs) within 1kpc, has targets selected from the whole sky, and is not biased by previous studies of star formation.2008AJ....135.2496Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/2496CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources, 2MASX (IPAC/UMass, 2003-2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/2496https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/2496http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/2496https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/2496https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/2496http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/2496GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/2496/table1 (Source characteristics)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/2496/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/2496/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/2496/table1?GETtext/xml+votable180.050000true5.23662562.67250.0055555555555555566/857 859 860 862 881 1037 1048 1050 1052 1054 1061 1074 1082 1154 1159 1231 1242 1243 1266 1287 1542 1589 1606 1613 1636 1846 1946 2794 2948 3011 3059 3301 3310 3459 3649 3735 3986 13736 13981 14052 14053 14263 14350 14353 15409 15421 15422 15476 15477 15479 15541 15585 15630 15649 15667 15668 15671 15682 15683 15684 15759 15790 15816 15857 15941 15964 15965 16129 16191 16197 16320 21285 21298 21303 21311 21325 21336 21353 21354 21396 21397 21400 21425 21428 21430 21435 21436 21438 21440 21445 21446 21458 21641 21646 21668 22620 22804 22805 22807 22855 22856 22861 22866 22876 23030 23533 23549 23637 23639 23644 23704 23738 23810 24493 29274 29367 29653 29673 30251 30252 30266 30316 30317 30319 30341 30343 30353 30355 30363 30402 30613 30733 30821 36956 37817 37845 37851 37855 37938 38447 38531 39163 39228 39258 39259 39280 39394 39405 39747 39899 39916 41132 41133 41559 41599 41661 41702 41707 41740 41744 41748 41759 42233 42546 42736 42738 42970 42981 43010 43013 43025 43444 47742 478285.0692151230857684e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/2496?format=asciiInfrareddefaultJ/AJ/135/2496/table5Binary propertiesrecnoRecord number assigned by the VizieR team.
