Notes. N is the number of spectra available for each target star. “RV rms” (respectively “BVS rms”) is the rms of the measured radial velocities (respectively bisector velocity-spans). “RV amp” (respectively “BVS amp.”) is the amplitude of the measured radial velocities (respectively bisector velocity-spans). “RV unc” (respectively “BVS unc”) is the average uncertainty associated to the RV (respectively bisector velocity-spans) data. The column labelled “bisector” provides a flag of the BVS quality: good (G), acceptable (A), bad (B), not enough point (NEP). The vsini have been computed from our data (see Sect. 3.2). The column labelled “Ca line” provides a classification of the Ca emission with respect to the stellar line depth as follows: strong, medium, small, no, absorption Ca line. The mean is indicated between parenthesis whenever possible. The variability classification is as follows: active (A), pulsating (P), high frequency RV variations (HFV), spectroscopic binary (SB), candidate companion (CC), not enough points (NEP). The slope of the (RV, BVS) is indicated between parenthesis for the most active stars. The detection limits are computed for periods of 3, 10, 100, 500, and 1000 days (whenever possible) using the LPA method on unaveraged data.
