cds-question@unistra.frvisible-astronomymedium-band-photometryvariable-starsThis is the first catalogue of photometric data in the Stroemgren system obtained during the period October 1982 - September 1986. Full description can be found in ESO report SP 8. Since our goal is not absolute (all-sky) photometry, the observations should be used for differential photometry only. The mean values of the r.m.s. deviations of the differential measurements of comparison stars are around (from Table 5 of paper) ------------------------------------ System y b-y m1 c1 ------------------------------------ 1 0.0109 0.0088 0.0133 0.0136 4 0.0068 0.0057 0.0079 0.0118 5 0.0087 0.0070 0.0114 0.0114 6 0.0090 0.0078 0.0126 0.0132 7 0.0071 0.0033 0.0041 0.0065 ------------------------------------1991A&AS...87..481Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/188 : Long-Term Photometry of Variables at ESO II (1993)II/200 : Long-Term Photometry of Variables at ESO III (1995)II/202 : Long-Term Photometry of Variables at ESO IV (1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/170https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/170http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/170https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/170https://vizier.iucaa.in/viz-bin/votable?-source=II/170http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/170GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/170/stars1 (The list of stars observed (10 stars missing))https://vizier.cds.unistra.fr/viz-bin/conesearch/II/170/stars1?https://vizier.iucaa.in/viz-bin/conesearch/II/170/stars1?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/170/stars1?GETtext/xml+votable180.050000true0.5125-2.768330.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/II/170?format=asciiOpticaldefaultII/170/ltpv1The Observationsymagmagnitudemagphot.mag;em.opt.VfloatrecnoRecord number assigned by the VizieR team.
