Comparison of line intensities and intensity ratios at the position of the Hα peak with plane-parallel constant density PDR models (Kaufman et al. 1999). Gray-scales show the estimated reduced χ2. The horizontal line shows the FUV estimated from the total FIR intensity. The contours correspond to the intensities/ratios of different spectral lines (as shown in the labels). The [C ii] intensity corresponds only to the estimated contribution (70% of the total) from the PDRs.
