cds-question@unistra.frvisible-astronomyWide-band photometrymedium-band-photometryob-starsThe Catalogue of Individual UBV and uvby-beta Observations of Stars in the Region of the Orion OB 1 Association presents individual UBV observations of 106 stars in the vicinity of the Orion Nebula (the Sword region) and individual uvby-beta observations of 508 stars in all regions of the Orion OB 1 association. For the UBV data the stars are identified by their Brun (1935) numbers, with cross identifications to the chart numbers used in Warren and Hesser (1977); the uvby-beta stars are identified by the aforementioned chart numbers and HD, BD or P (Parenago 1954) numbers in that order of preference. The catalogue contains the data of all observations and is intended to provide data for investigations of variability in the Orion region. See <http://obswww.unige.ch/gcpd/ph01.html> for a full description of the UBV system, and <http://obswww.unige.ch/gcpd/ph04.html> for a description of uvby-beta system.1977ApJS...34..115Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/171 : Parenago Catalogue of stars in the area of Ori Nebulahttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/36https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/36https://vizier.iucaa.in/viz-bin/votable?-source=II/36http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/36/ubv (UBV data)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/36/ubv?https://vizier.iucaa.in/viz-bin/conesearch/II/36/ubv?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/36/ubv?GETtext/xml+votable180.050000true83.20692-5.25471060.005555555555555556Cone search capability for table II/36/uvbybeta (uvby-beta data)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/36/uvbybeta?https://vizier.iucaa.in/viz-bin/conesearch/II/36/uvbybeta?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/36/uvbybeta?GETtext/xml+votable180.050000true76.59546142.67326060.0055555555555555564/1428 5/5358 5359 5701 5718 5721 5723 5726 5748 6/21406 21425 21427 21428 21430 21431 21450 21472 21473 21478 21480 21482 21483 21486 22800 22801 22812 22813 22815 22829 22833 22836 22837 22839 22844 22870 22871 22876 22878 22879 22880 22881 22883 22888 22889 22890 22896 22897 22898 22902 22908 22911 22935 22979 22981 22986 22991 22997 22998 23000 23003 23005 23013 23024 23560 23586 23587 23590 23591 23594 23595 23680 23682 236883.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/36?format=asciiOpticaldefaultII/36/ubvUBV datarecnoRecord number assigned by the VizieR team.
