Results based on the ρ Ophiuchi cloud model at (θ, ϕ) = (0°, 0°) (top) and (θ, ϕ) = (45°, 45°) (bottom). From left to right the figures show the maps of synthetic intensity at 250 μm, maps of effective total column density with corresponding PDFs, and the maps of effective dust temperature with corresponding PDF. The contours in the maps are at {0.82,1.0,1.15,1.32,1.5}, {22.0,22.32,22.72,23.0}, and {10.5,11.0,11.5,12.0} K. The red lines in the PDFs indicate the arithmetic mean values of the distributions, the blue lines the median values.
