Notes. The corresponding reduced χ2 and the rms value of the scatter around each fit are listed as well. The listed offsets for the CFHT, DAO, TLS, BOAO and McDonald data sets are the offsets relative to the offset-corrected published RV data of H15 while the Lick offset refers to the non-offset-corrected RV values in Table B.1.
