Distribution of temperature and κ for each majority population of a certain type of ICME. A KDE plot is also provided in each subplot together with related histograms. For the histograms, there are 40 bins. κ here has been filtered to be no more than 5. The proportion of each data set that meets this criteria is as follows: (a) Type C_β (66.7% C₁, 28.2% C₂). (b) Type C_α (77.9% C₁, 22.1% C₂, 21.4% C₃). (c) Type H_β (70.8% C₁, 41.7% C₂, 66.7% H). (d) Type H_α (83.0% C₁, 26.4% C₂, 24.5% C₃, 86.8% H).
