We have compared the Hyades, Coma, and a set of field standard stars in the V and Stromgren-beta systems. If Stromgren data by Crawford and his collaborators (1966, 1969, 1970) are considered, all the data turn out to be on the same system; no corrections as large as several mmag are required to achieve this state. For beta, similar consistency between the Hyades and Coma is already known to exist. We find that for the standard stars, beta values from the literature are consistent with the Hyades-Coma system. For V, we adopt corrections derived previously by Joner and Taylor (1990) for published cluster photometry. Given these corrections, we find that within rather generous accidental-error limits, the V systems for the field stars and the clusters agree.
