The spectral classification and the H{alpha} emission features were measured on objective-prism plates taken with the 60/80/180 Schmidt telescope; the photometry was derived from observations made on photographic plates with emulsion-filter combinations giving magnitudes in the Johnson photometric system. The distance of the cloud was found to be 300+/-50pc.1993A&A...272..235Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/272/235CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/272/235https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/272/235http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/272/235https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/272/235https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/272/235http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/272/235GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/272/235/table1 (*Field stars around L1251)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/272/235/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/272/235/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/272/235/table1?GETtext/xml+votable180.050000true338.063708375.31122220.005555555555555556Cone search capability for table J/A+A/272/235/table2 (H{alpha} emission stars in L1251)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/272/235/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/272/235/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/272/235/table2?GETtext/xml+votable180.050000true338.55034775.3027120.005555555555555556Cone search capability for table J/A+A/272/235/table3 (IRAS point sources in L1251)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/272/235/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/272/235/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/272/235/table3?GETtext/xml+votable180.050000true337.07404575.1327860.0055555555555555565/4049 6/1.6558465556080236e-21 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/272/235?format=asciiOpticaldefaultJ/A+A/272/235/table1*Field stars around L1251recnoRecord number assigned by the VizieR team.
