[Fe/H] as a function of the orbital period (left panel) and eccentricity (right panel). Stars are plotted with different colours and increasing sizes with increasing planet minimum mass. Median uncertainties are 0.6 MJup for the planetary minimum mass, 0.6 day for the planetary periods, 0.04 for the eccentricities, and 0.02 dex for [Fe/H].
