Fig. 8


Left: foreground-corrected dust column-density map (as shown in Fig. 1) in greyscale. The black contour indicates the Av = 15 level. The red contours show the same Av = 15 level from the H2 column-density map derived from N2H+, using an excitation temperature of 10 K and an abundance of 2 × 10-9. Right: dust temperature map of Cygnus X North from Herschel with the same red Av = 15 contour from N2H+.
