Appendix A

Appendix A.1: PACS spatial pixel emissions

[O i] 63 μm spectrum for each pixel in the PACS spectrometer array. The PACS integral filed unit has a 47′′ × 47′′ field of view. Each 25 pixels has a 9.4′′ × 9.4′′ spatial resolution. The flux is emitted in the central spaxels.

Appendix A.2: Collisional data

The original articles for the line frequencies, Einstein coefficients, and collisional rates are CO (Flower 2001; Jankowski & Szalewicz 2005; Yang et al. 2006; Wernli et al. 2006), H2O (Barber et al. 2006; Dubernet & Grosjean 2002; Faure et al. 2004, 2007; Daniel et al. 2011), O i (Abrahamsson et al. 2007; Bell et al. 1998; Chambaud et al. 1980; Jaquet et al. 1992; Launay & Roueff 1977), C ii (Flower & Launay 1977; Launay & Roueff 1977; Wilson & Bell 2002), CH+ (Müller 2010; Lim et al. 1999; Hammami et al. 2009; Turpin et al. 2010), OH (Offer et al. 1994).

Appendix A.3: Photometric data

We provide the photometric data used in our SED modeling in Table A.1.
