The columns give Cannon & Lloyd's (1970) identification, V and B-V (V values with a leading parenthesis are photographic), the mean radial velocity ($V_{\rm r}$) and the error on the mean ($\epsilon$) in km s-1, the number of observations, N, the probability $P(\chi^2)$ of variability from Coravel. Columns (9) to (15) reproduce literature data, RVs ( $RV_{\rm lit}$) and errors ($\sigma$) in km s-1, the number of observations (n), the difference with Coravel results (Diff), the sources (Src) (mcc: McClure & Woodsworth 1990; lj: Liu & Janes 1987; ss: Smith & Suntzeff 1987), RVs from Scott et al. (1995), (SFJ) and Cameron & Reid (1987), (CCR). The last column provides notes on binarity (SB: spectroscopic binary) and membership (NM: non-member).
