Far IR spectral energy distribution of IC 63 and IC 59 compared to that of the Horsehead PDR (G₀ = 100 and T_dust = 23.3 K for a spectral index β = 0.99; Ochsendorf & Tielens 2015), and NGC7023 eastern (E) and north (N) PDRs (G₀ = 250 and 2600, and T_dust ~ 20 and 30 K, respectively assuming β = 2; Köhler et al. 2014). Also shown is the SED derived for the cirrus cloud in the diffuse ISM (Compiègne et al. 2010). For IC 63 we found G₀ = 150 and T_dust ~ 30 K, while for IC 59 we derive values of G₀ = 25 and T_dust = 27 K.
