Fig. 2
Left: surface brightness at 3.6 μm as a function of extinction for the model cores. The solid line is the average surface brightness. The dashed line is from a linear interpolation of the very optically thin case. Right: the correction factor for the adopted sample based on the ratio of the extrapolated and model surface brightness from the left.
