Notes. .

^(a)

We give the median velocity precision of the observations, and not the best precision that can be attained with the given instrument. The FIES and TRES observations of HAT-P-43 were done in reconnaissance mode (lower S/N) which so they yield velocities that are less precise than the SOPHIE observations.

^(b)

A precision of 30 m s^-1, plus 35 m s^-1 added in quadrature to achieve a χ² per degree of freedom of unity for the Keplerian fit of HAT-P-42

^(c)

Values within parentheses include the sum of the theoretical noise due to the instrument (6 and 10 m s^-1, respectively), plus empirical errors taking into account the correction due to moonlight in the spectra.
