cds-question@unistra.frvisible-astronomymedium-band-photometryearly-type-starsStroemgren and H{beta} photometry of OB-stars generally brighter than 9.5mag in the Canis Major - Puppis - Vela region of Milky Way is reported. The observations are based on the Milky Way luminous-star (LS) identifications and are designed to create a complete, magnitude-limited sample of LS for this field. We present new uvby photometry for 127 LS and H{beta} photometry for 25 of them. These observations are part of an ongoing effort to improve the completeness of the existing uvby{beta} data-base for the bright OB-type stars in the Milky Way, with the aim to investigate the structure of selected star-forming regions.1999A&A...352..600Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/352/600CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/76 : Luminous Stars in the Northern Milky WayIII/43 : Luminous Stars in the Southern Milky Way (Stephenson+ 1971)J/A+A/352/605 : O & B stars uvby-Hbeta photometry.
