Notes. The numbers of points are the total and, below, the number before+after the 2015 upgrade. All these points are night-averaged. The rms columns provide the post-fit RV dispersions, both before and after the fibre upgrade. All the rms are in m s−1. The timespans Δt are in days. Arrows mean “std value” → “new value”. “n pl.” means n planetary (Keplerian) signals; “MC” means “magnetic cycle”, also fitted by a Keplerian signal unless stated otherwise.
