Properties of the PAH clouds vs galactocentric radius per environment for all the clouds in the 66 galaxies: Σ_mol (left), M_mol (middle), and R_eq (right). The running median property per galaxy median (dashed line) is plotted for a bin width of 0.2 R_e. The shaded region represents the 84-50th and 50-16th percentiles of the medians per galaxy. The error bars on the median are the standard errors (1.253σ/$\sqrt{N}$), where N is the number of galaxies contributing to a specific bin.
