cds-question@unistra.frvariable-starsvisible-astronomyphotographic-photometry621 new variable stars have been detected on plates obtained with the Schmidt telescopes of the Mount Palomar Observatory (1968) and of the European Southern Observatory (1976-1980). The astrometric measurements (ESO-CERN) and the photometrical ones (CDCA) which have followed the detection the variable stars (Observatoire de Lyon) have led to determine the parameters {alpha}, {delta}, l, b, R(Max), R(Min), {delta}m. So we notice that: - 379 variable stars have an amplitude of variation in magnitude between 0.5 and 2.0 (delm/N histogram). -The number of variable stars strongly decreases towards the great amplitudes. -The surface density of variable stars by square degree in this central galactic direction increases from 2 to 21 in the explored field of 5.5degx5.5deg size.1982A&AS...49..715Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/49/715CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/49/715https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/49/715http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/49/715https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/49/715https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/49/715http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/49/715GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/49/715/table2 (Photometric sequence)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/49/715/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/49/715/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/49/715/table2?GETtext/xml+votable180.050000true263.265799-29.1204870.005555555555555556Cone search capability for table J/A+AS/49/715/table3 (Catalogue of 621 Variable Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/49/715/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/49/715/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/49/715/table3?GETtext/xml+votable180.050000true259.257382-32.1040650.0055555555555555565/7209-7211 6/28814 28833-28835 28848 28850-28851 28856-28858 29185 29187-29190 42487 42492-42493https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/49/715?format=asciiOpticaldefaultJ/A+AS/49/715/table2Photometric sequencerecnoRecord number assigned by the VizieR team.
