Histograms of hot Jupiter (HJ) system properties. We compare the targets analysed within the scope of this study (orange bars) to a general sample of hot Jupiter environments (blue bars). Top panel: relative frequency distributions of stellar masses M_⋆, radii R_⋆, and effective temperatures T_eff amongst both samples. Lower panel: properties of the transiting companions such as planetary masses M_p, planetary radii R_p, and orbital periods P. In the upper part of each plot, we present the 68% confidence intervals around the medians of the corresponding distributions.
