Resolved scaling relations of dust mass surface density with the atomic (left panel), molecular (middle panel) and total gas (right panel) surface density. Each galaxy is represented by a different colour. The median uncertainties for each galaxy are shown in the lower right or lower left corner of the panels. The solid lines are the best linear fits to the full sample, while the shaded grey area indicates the fit uncertainty. The slope, intercept, and scatter of each fit are also given along with the correlation coefficients. In the right panel open circles show pixels where only H I is detected.
