Hyades and Sirius supercluster members brighter than magnitude (V) 7.1.I. The first six hours of right ascension.
This is the first of four papers listing the probable members of the Hyades and Sirius superclusters among stars brighter than V = 7.1 mag. The star sample is contained in the Bright Star Catalogue and its Supplement, augmented with a further supplement of 550 stars found during various observing programs over the past 40 years. Accurate, four-color and H-beta, or (RI), photometry is available for most of the supercluster members. The criteria for membership are the comparisons of the proper motion, radial velocity, and luminosity obtained from the supercluster parameters with the observed motions and the luminosity derived from the photometric parameters. New proper motions, based on all available catalogs, have been derived for the additional 550 stars discussed here, as well as for all supercluster members.
