Temperatures Tℐ and masses Mℐ derived from fitting images ℐν of both isolated and embedded starless cores vs. the true model values of TM 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 Φn of pixel intensities. Error bars represent the 1 × σ uncertainties of the derived Tℐ and Mℐ (computed over all pixels as the NH2-averaged errors of TNij and integrated errors of NH2, 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.
