A Reference List for the UBV System
Listed in IVOA Registry (Virtual Observatory)
This catalog is a file of 13422 records giving for each star, an identification, V, B-V, and U-B. Care was taken to place all measurements on the Johnson UBV system by determining possible systematic differences between measurements by Johnson and those by other observers.
Description
Introduction: The list of Johnson et al. (1966) of 4777 stars was considered as fundamental and given absolute priority. The differences between these data and those for the same stars in other lists in which Johnson was a coauthor were used to determine the systematic corrections and the dispersions were used to determine the weight for each of these lists.
Finally, other lists were treated in the same way with absolute priority given to those data in the lists with Johnson as a coauthor.
