Notes. The global PDR conditions in PLCK_G045.1+61.1, obtained from the line ratios illustrated in Fig. 8, are consistent with those in the brightest of the four multiple images (Nesvadba et al. 2016). Average PDR surface temperatures are deduced from the source position in the nPDR − G0 parameter space. The last column lists rough estimates of the PDR sizes following Wolfire et al. (1990) and Stacey et al. (2010), discussed further in Sect. 6.2.
