Pixel-by-pixel relationships between the derived dust properties, Σdust (upper panels) and Tdust (lower panels), and the surface densities of the gaseous ISM components: ΣHi (left), ΣH2 (middle) and Σgas (right). We differentiate between on- and off-axis pixels using solid and open circles, respectively. The best linear fits are indicated by the solid red lines. Error bars are calculated from the standard deviations of the errors on individual pixels and the ρ values are the corresponding Spearman correlation coefficients.
