| Four-colour UVBY and H-beta photometry of all A3 to F5 stars brighter than m(pg) = about 11.0 mag in 6 Selected Areas close to the Galactic plane
Photometric observations of 540 A3-F5 stars in Selected Areas 171, 173,175, 177, 192, and 195 of the Potsdam survey (Becker and Brueck,1929-1938) are reported. Data obtained in the Stromgren uvby-beta systemusing a 6-channel spectrograph-photometer on the 50-cm Danish telescopeat ESO on 98 nights during 1986-1987 are presented in extensive tablesand graphs and briefly characterized. Comparisons with previousobservations of some program stars reveal no systematic differences inmagnitude or spectral indices.
| Hyades and Sirius supercluster members brighter than magnitude (V) 7.1. II - Right ascension six to twelve hours
The present star sample is contained in the Bright Star Catalogue andits Supplement, augmented with a further supplement of 788 stars foundduring various observing programs over the past 40 years. Accurate,four-color and H-beta, or (RI), photometry is available for most of thesupercluster members. The criteria for membership are the comparisons ofthe proper motion, radial velocity, and luminosity obtained from thesupercluster parameters with the observed motions and the luminosityderived from the photometric parameters. New proper motions, based onall available catalogs, have been derived for the additional 788 starsdiscussed here, as well as all supercluster members.
