cds-question@unistra.freclipsing-binary-starsWe report CCD measurements of 33 visual double stars observed at the 1-meter coude reflector of the Observatorio de Llano del Hato located at Merida, Venezuela. We also present an algorithm to determine the stars' centroids for superimposed images as well as a brief comparison of accuracies attained by the algorithm and the program CENTER of the IRAF package.1995A&AS..111..229Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/111/229CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/111/229https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/111/229http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/111/229https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/111/229https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/111/229http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/111/229GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/111/229/table1 (CCD measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/111/229/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/111/229/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/111/229/table1?GETtext/xml+votable180.050000true48.025-28.98330.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/111/229?format=asciiOpticaldefaultJ/A+AS/111/229/table1CCD measurementsrecnoRecord number assigned by the VizieR team.
