cds-question@unistra.freclipsing-binary-starsvisible-astronomymedium-band-photometryTable 1 contents 471 simultaneous measurements collected in each of the four uvby colours of the Stroemgren photometric system for the eclipsing binary system AB Cas. Because of an instrumental problem, 82 points in the b channel (during the last observational night) had to be rejected (the corresponding magnitudes are listed as 0.0000). The data are magnitude differences (Du,Dv,Db,Dy) of the variable star minus comparison star in the instrumental system versus Heliocentric Julian Day. Table 2 is the same, but for H{beta} (80 points). The comparison star is BD+70 0188. The origin in time is the Julian Day 2447117. The observations were carried out (by E. Rodriguez, A. Claret, J.L. Sedano, J.M. Garcia and R. Garrido) during 1987 and 1988 using the 0.90m telescope at the Sierra Nevada Observatory, Spain.1998A&A...340..196Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/340/196CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/340/196https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/340/196http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/340/196https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/340/196https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/340/196http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/340/196GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/340/196/table1uvby differential photometryrecnoRecord number assigned by the VizieR team.
