Histogram of the parameters of the majority populations. From top to bottom are subplots for Type C_β, Type C_α, Type H_β, and Type H_α. From left to right are histograms for temperature, relative abundance, and κ of the majority populations that come from corresponding types with 50 bins, and bin ranges of [5.65, 7.2], [0.1, 0.9], and [1.55, 33], respectively. Different colors represent different populations in each type and populations are named independently; e.g., C_β-p_c1 represents cool population number one in C_β, and H_β-p_h represents hot population in Type H_β. The black dash line marks the temperature threshold to distinguish cool and hot populations, which is 4 MK.
