Distributions of the parameters of 2D Plummer profiles for the sub-sample of 85 clumps. Scatterplots and correlations are shown between geometric mean of the flat radius values ⟨R⟩, ratio of flat radius values R₂∕R₁, power-law exponent p, peak optical depth τ(250 μm), background optical depth τ_BG(250 μm), and distance. The frames on the diagonal show the histograms of the individual quantities and the frames in the upper right hand part of the figure indicate the linear correlation coefficients for the corresponding pairs of parameters.
