Correlation between the H2-to-dust ratio and the dust temperature. The best linear fits are indicated by the solid red lines, with the mean ΣH2/ Σdust ratio represented by the dashed black line. The cluster of points with ΣH2/ Σdust ratio lower than the mean and possessing a higher dust temperature (Tdust> 23.5 K, shown by the dotted black line) are all central pixels.
