cds-question@unistra.frearly-type-starsvisible-astronomymedium-band-photometryStroemgren and H{beta} photometry of O and B type stars, generally brighter than 9.5 mag is reported for the field of the Carina Spiral Feature. The observations are based on the PPM (Cat. <I/193>) catalogue identifications and are designed to improve the completeness of the existing uvby{beta} data for the bright early-type stars in the field. We present new uvby photometry for 283 stars and H{beta} photometry for 225 of them. These observations are part of an ongoing effort to study the structure of selected star-forming regions in the Milky Way by means of uvby{beta} photometry. A comparison of the new data to other uvby{beta} data sets for this field is presented.2000A&AS..146..365Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/146/365CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/352/600 : O + B stars uvby-Hbeta photometry.
