Two-dimensional gas temperature, dust temperature, gas density, and the UV radiation field structure in the best fit model. The white solid contours correspond to the gas temperature of 330 and 650 K. The grey and green contours represent where the dust emission at 13.7 and 10 µm is coming from. The black contour corresponds to the radial A_v of 1 mag. The white dashed contours correspond to the value of the ticks on the colour bar.
