Notes. If not noted otherwise, these parameters are kept fixed for all our models presented in this work. For more details on the parameter definitions see Woitke et al. (2009, 2011, 2016).
χISM is given in units of the Draine field (Draine & Bertoldi 1996; Woitke et al. 2009).
We use distributed hollow spheres for the dust opacity calculations (Min et al. 2005, 2016).
