Notes. Significant trends and sinusoidal periods are printed in bold face (FAP < 1%0). An index “r” to the name of the star (first column) indicates tests on the residuals as derived from the most significant model to the original data. Listed are the number of binned observations Nbin, the combined time baseline T, the mean combined noise term σ (including jitter), the combined weighted rms of the time series, the flag S for the probable main source of the RV variations as concluded in this work in Sect. 5 (A – activity, B – binary/wide stellar companion, P – planet), the χ2-probability for fitting a constant, and the false alarm probabilities (FAP) for the other tests. Also listed are the weighted scatter of the residuals (rmsslope, rmssin, rmsKep) and some best-fitting parameters (slope and the periods Psin and PKep).
