Parameters of the best-fit models.

T b Ωb T g λ 0 β Ωg
B1- (K) (′′/10) (K) (μm) (′′)

bS 29.0 5.25 8.0  ±  0.5 100 2.00  ±  0.25 20.4
bN 33.0 1.94+0.94 8.0  ±  0.5 120  ±  45 2.00  ±  0.25 17

Notes. Tb and Ωb are the temperature and the solid angle of the blackbody; Tg, λ0, β and Ωg are the parameters of the greybody (see Appendix A). Ωb and Ωg are given as radii . Uncertainties are 1σ. The χ2 are 5.2 and 4.0 for B1-bS and B1-bN, respectively. For B1-bN, the best-fit model has the smallest Ωb, so we do not have an estimate for the lower uncertainty.
