The strength of their pulsational driving strongly depends on the opacity of iron-group elements. As many of those stars naturally occur in young open clusters, whose metallicities can be determined in several fundamental ways, it is logical to study the incidence of pulsation in several young open clusters. To provide the foundation for such an investigation, Stroemgren-Crawford uvby{beta} photometry of open cluster target stars was carried out to determine effective temperatures, luminosities, and therefore cluster memberships. In the course of three observing runs, uvby{beta} photometry for 168 target stars was acquired and transformed into the standard system by measurements of 117 standard stars. The list of target stars also included some known cluster and field {beta} Cephei stars, as well as {beta} Cephei and SPB candidates that are targets of the asteroseismic part of the Kepler satellite mission. The uvby{beta} photometric results are presented. The data are shown to be on the standard system, and the properties of the target stars are discussed: 140 of these are indeed OB stars, a total of 101 targets lie within the {beta} Cephei and/or SPB star instability strips, and each investigated cluster contains such potential pulsators. These measurements will be taken advantage of in a number of subsequent publications.2011A&A...528A.148Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/528/A148CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/528/A148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/528/A148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/528/A148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/528/A148https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/528/A148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/528/A148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/528/A148/tables (uvbybeta photometry of standard stars (table 3), open cluster target stars (table 4), known {beta} Cep and other target stars (table 5) and early-type stars (table 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/528/A148/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/528/A148/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/528/A148/tables?GETtext/xml+votable180.050000true276.0858333-10.80944440.0055555555555555566/1285 1287 1298 2409 3214 3247 3256-3258 3307 3384 3623 3638 3723 12400 13255 13531 13533-13535 13553-13554 13556 13559 13565 13703 13706 13708 13728-13730 13736 13746 13751 14079 14129 14179 14240 14263 14303 14356 14456 14579 14583 14587 14630 14633 14645 14690 14731 14733 14744 14751-14752 14754 14770-14773 14776-14777 14781 14783 14827 14919 14925 14934 14940 14942 14960 14963 15106 15109 15112 15129 15137 15146 15170 15172 15178 15622 15656 15681 15683-15684 15686 15689 15691 17067 22249 22252 23769 29025 29097 29114 29460 29517 30302 31071 31787 31794 320683.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/528/A148?format=asciiOpticaldefaultJ/A+A/528/A148/tablesuvbybeta photometry of standard stars (table 3), open cluster target stars (table 4), known {beta} Cep and other target stars (table 5) and early-type stars (table 6)SimbadNameSimbad column added by the CDSmeta.idcharc1? c1 indexmagphot.colorfloatnullablerecnoRecord number assigned by the VizieR team.
