Spatial variations of the dust opacities (left) and specific power (right) with the total gas measured by N_{H γ} at 0.̊375 resolution (top) and by N_{H mλ} at 0.̊125 resolution (bottom). The tilded quantities are convolved with the LAT response for an interstellar spectrum. The black contours outline the shape of the CO clouds at the 7 K km s^-1 level chosen to separate DNM and CO_sat components.
