cds-question@unistra.frinterstellar-mediummolecular-cloudsco-line-emissionWe have studied the ratio of carbon monoxide column density to the extinction A_J_ of background field stars in the direction of three globules: B133, B335, L466. The N(CO) to A_J_ ratios were found to vary from cloud to cloud so that they are larger in B335 than in B133 and L466. These variations are thought to primarily arise from variations of the ratio N(CO)/N(H_2_).2004A&A...421.1087Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/421/1087CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/421/1087https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/421/1087http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/421/1087https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/421/1087https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/421/1087http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/421/1087GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/421/1087/table1 (Positions observed with SEST and the J band extinctions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/421/1087/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/421/1087/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/421/1087/table1?GETtext/xml+votable180.050000true294.2125437.5842280.0055555555555555566/29566 29881 29884 30519https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/421/1087?format=asciiRadiodefaultJ/A+A/421/1087/table1Positions observed with SEST and the J band extinctionsNameName of observed positionmeta.id;poscharGlobuleGlobule namemeta.id.parentcharrecnoRecord number assigned by the VizieR team.
