cds-question@unistra.frvisible-astronomymedium-band-photometryearly-type-starsWe present Stroemgren uvby and H_{beta}_ photometry for a set of 575 northern main sequence A type stars, most of them belonging to the Hipparcos Input Catalogue, with V from 5mag to 10mag and with known radial velocities. These observations enlarge the catalogue we began to compile some years ago to more than 1500 stars. Our catalogue includes kinematic and astrophysical data for each star. Our future goal is to perform an accurate analysis of the kinematical behaviour of these stars in the solar neighbourhood.1996A&AS..115..401Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/115/401CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/115/401https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/115/401http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/115/401https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/115/401https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/115/401http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/115/401GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/115/401/standardPhotometry of the standard stars (tables 1-4)recnoRecord number assigned by the VizieR team.
