Left column: histograms of skewness, kurtosis, and Gini measured from the local PDFs in optical, FIR, and MIR data. Fainter histograms represent smaller kernel scales used for PDF extraction. Middle column: histograms showing the distributions of differences of the statistics between FIR or MIR and optical data. The difference is calculated by [optical-X], where X stands for the band. Right column: mean absolute difference of statistics between FIR or MIR and optical as a function of kernel scale.
