Parameters of the best-fit Draine and newdust models considering different scattering components.

Component	Draine	newdust	newdust	newdust	newdust
	sheet	sheet	uniform	uniform+sheet	Lallement et al. (2019)
PSF normalization	1.00(8)	1.02(8)	1.04(7)	1.02(8)	0.98(8)
Background level	0.07(2)	0.06(2)	0.08(2)	0.07(2)	0.07(2)
x_D	0.75(11)	0.75(12)		0.69(24)
D_CCO∕kpc					2.79(62)
N_H∕10²² cm⁻²	2.00(3)	2.00(3)	2.00(3)	2.00(3)	2.00(3)
log Z	–3.9	–4.1	–4.1	–4.1	–3.4
Δlog Z	–0.5	–0.7	–0.7	–0.7	0

Notes. log Z and Δ log Z indicate marginal likelihoods (global evidences) and their differences with respect to the statistically preferred realistic dust distribution model, respectively.
