Dust temperatures Td for grains at the location of region 1, the outer dust wave (ODW), and the inner dust wave (IDW), derived through 1) a modified-blackbody fit (MBB) and 2) DUSTEM modeling of the equilibrium temperature for a 0.1 μm silicate grain and 1.0 μm silicate grain (Teq,S) and amorphous carbon grain (Teq,C).

Notes. Also listed are the projected distance d, and the hardness of the radiation field, G0 (Habing 1968). The observed cold component Td,C is calculated with β as a free parameter (see Fig. 4), and by choosing β = 1.5 as given by the Planck dust model (Planck Collaboration XI 2014), denoted between brackets.
