cds-question@unistra.freclipsing-binary-starsearly-type-starsvisible-astronomybroad-band-photometryUBV measurements of early-type stars, mostly eclipsing binaries, obtained at La Silla in the years 1990 to 1994 with the ESO 50cm telescope are presented. Most of these data were already used in our individual studies of several binaries. Now all photometric measurements were reduced again with an advanced technique and are made available electronically. Our data for MY Ser have not yet been published; new light curve is given and solved. The result is that MY Ser is a contact binary, with very large fill-out parameter. Also a light curve and its solution for V1051 Cen are provided, and the problem of the period of V871 Cen is pointed out. Besides binaries (and the comparison and check stars) data for several stars in southern H II regions are included. Extinction and transformation coefficients are given.2010AN....331..274Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/331/274CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/331/274https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/331/274http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/331/274https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/331/274https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/331/274http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/331/274GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/331/274/stars (List of variable and check stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/331/274/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/331/274/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/331/274/stars?GETtext/xml+votable180.050000true184.404583-58.1644440.0055555555555555566/21643 22517 28913 28916 29513 30268 30627 37869 37881 37897 37900 37910 37923 38016 39274 41705-41706 42394 43140 431483.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/331/274?format=asciiOpticaldefaultJ/AN/331/274/starsList of variable and check starsLCDisplay the UBV light curvesmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
