Quantities averaged along the LOS derived by POLARIS MC simulations for the ISRF-RAT setup. Here, direct averages are done, without any weighting by another parameter. The individual panels show the alignment radius a_alig (top left), average dust temperature T_dust (top right), G₀ (middle left), the radiation field U_rad (middle right), the average angle (bottom left), and the anisotropy factor (bottom right), respectively.
