Notes: Individual columns report dates of observation, instrument, number of averaged Stokes V series, mean peak S/N in Stokes I for one spectrum, mean HJD, Phase according to Hatzes et al. (2006),
and its error in G, the S-index for Ca II H and K, and the radial velocity measured from the LSD Stokes I profile.
