cds-question@unistra.frmultiple-starsccd-photometryWe present photometric and astrometric data of about 280 visual double stars of the "intermediate" class, i.e. with angular separations mainly in the range 2"<{rho}<12". The observations have been obtained in 1991-92 with a CCD camera attached to the 91cm Dutch telescope at ESO La Silla, Chile. Differential magnitudes of the double star components as well as magnitudes and colour indices of the individual components have been determined in the Cousins V and I passbands with an internal error of about 0.005mag and an external accuracy of less than 0.03mag. In addition, angular separations have been secured to an internal accuracy of 0.004" and position angles to about 0.05{deg}.1999A&AS..139..425Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/139/425CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/139/425https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/139/425http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/139/425https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/139/425https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/139/425http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/139/425GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/139/425/table3Photometric results (V and I) of the CCD observations for visual binariesNote2Note to table3.dat (2)charJDJulian dateddoublerecnoRecord number assigned by the VizieR team.
