Fig. 5: PDR model results.

The panels show the parameter space of hydrogen density n and FUV field calculated from the PDR toolbox. a, The dark blue isocontour of the observed [CII] integrated intensity of 5 K km s−1 and the noise r.m.s. of 0.6 K km s−1 in dashed light blue. The estimated FUV field of 10 G∘ is indicated by a red line. The dotted red lines indicate approximately a FUV field of double and half the value. b, The isocontours of surface temperature from the PDR model. For an average density of roughly 100 cm−3 (blue line) and a FUV field of roughly 10 G∘ (red line), we obtain a temperature of 115 K. The dashed lines for density and temperature indicate how these values change if the FUV field is higher or lower.
