Observed velocity dispersions of the 53 stars in our sample. The two planet hosts are indicated by the solid red boxes. We note that while Pr0201 resides in the upper tail of the distribution, other stars with similar rms values do not necessarily host planets; large internal errors and larger than average jitter are two possible reasons for a large rms. For reference, a 1 M _Jup planet in a 3 day orbit around a 1 M _☉ star has a full orbital amplitude of 281.7 m s ⁻¹.
