Notes. σjit,τ is the weighted 15 scatter of the HARPS data in the 2 h bins and τ is the weighted 16 mean of the time coverage in these bins (which may not cover the real jitter time scales in all cases). and activity index SHK are median values from the HARPS data of this work. The jitter estimation on long time scales σjit,long was derived as described in Isaacson & Fischer (2010) using B − V (Perryman et al. 1997) and SHK (this work). For comparison some literature SHK values are given ([H] Henry et al. 1996; [G] Gray et al. 2006; [W] Wright et al. 2004) and the jitter σjit,IF10 (“quadrature difference of velocity rms minus the formal internal errors”) as given by Isaacson & Fischer (2010) for stars monitored with Keck.
