cds-question@unistra.frvisible-astronomymedium-band-photometrymultiple-starsThe catalogue contains mainly two types of visual double stars: Evolved stars with main sequence companions; and systems, for which the IDS gives photometric and spectroscopic data, that suggest the secondary to be above the main sequence if the primary is placed on the main sequence. The photometry has been done with the Danish 50 cm reflector on La Silla, ESO, the limiting magnitude is 12m, separations are larger than 7". Identifications given are IDS, HD, and DM numbers. For each object V, b-y, ml, cl, and beta are given together with the number of nights, weights and r.m.s. errors of one observation (weight 1). The catalogue is published as table IV by E.H. Olsen, Astron. Astrophys. Suppl. 48, 165, where further details and discussion may be found.1982A&AS...48..165Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/78CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/78https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/78http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/78https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/78https://vizier.iucaa.in/viz-bin/votable?-source=II/78http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/78GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultII/78/datauvby-beta photometry on standard visual double or multiple systems (table 4)recnoRecord number assigned by the VizieR team.
