Correlation diagrams for the strength of three spectral features surveyed on Callisto in this work, namely the 4.25 µm CO2 absorption, the 3.1 µm H2O ice Fresnel peak, and the 4.57 µm absorption band. The presented r values are the Spearman rank-order correlation coefficients, which can vary between −1 and +1, where 0 implies no correlation.
