Distribution of eccentricities for all planets more massive than 0.3 M _J interior to the snow line (left panels) and exterior to the snow line (right panels). For the top two panels, both the shade and the size of the plotted data are logarithmically proportional to the planet mass, where dark green indicates a low mass and light green indicates a high mass. The bottom two panels show the histograms of the eccentricity data appearing in the top two panels.
