Temperatures T_ℐ and masses M_ℐ derived from fitting images ℐ_ν of both isolated and embedded starless cores vs. the true model values of T_M and M for correct β = 2. The three columns of panels present results for three angular resolutions (resolved, partially resolved, and unresolved cases) and for various subsets Φ_n of pixel intensities. Error bars represent the 1 × σ uncertainties of the derived T_ℐ and M_ℐ (computed over all pixels as the N_H2-averaged errors of T_Nij and integrated errors of N_H2, correspondingly), combined with the assumed ± 20% uncertainties of η, κ₀, and D (Sect. 3.4). Less reliable results (n−γ + 1 <χ²< 10 in some pixels) are shown without error bars. See Fig. 6 for more details.
