cds-question@unistra.frmolecular-cloudsvilnius-photometrySpectral and luminosity classes, absolute magnitudes. color excesses, interstellar extinctions and distances are determined for 98 stars down to 13mag in the Barnard 1 dark cloud belonging to the Per OB2 association. The classification of stars is based on their photoelectric photometry in the Vilnius seven-color photometric system. The extinction vs. distance diagram exhibits the presence of two dust layers at 150 and 230pc distances. The distance of the first cloud, which gives an extinction AV of 0.3mag, coincides with the distance of the Taurus dark cloud complex. The second cloud with much larger extinction is about at the same distance as the clouds in the direction of the nearby objects: reflection nebula NGC 1333 and open cluster IC 348.2003BaltA..12..301Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/BaltA/12/301CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/BaltA/12/301https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/BaltA/12/301http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/BaltA/12/301https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/BaltA/12/301https://vizier.iucaa.in/viz-bin/votable?-source=J/BaltA/12/301http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/BaltA/12/301GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/BaltA/12/301/tables (Photometry, color excesses and extinctions in Barnard 1)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/BaltA/12/301/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/BaltA/12/301/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/BaltA/12/301/tables?GETtext/xml+votable180.050000true52.087529.798330.0055555555555555565/215 6/854-857 1544https://cdsarc.cds.unistra.fr/viz-bin/moc/J/BaltA/12/301?format=asciiOpticaldefaultJ/BaltA/12/301/tablesPhotometry, color excesses and extinctions in Barnard 1recnoRecord number assigned by the VizieR team.
