Total flux within the 4σ contours of the 7M+TM2 PBCOR images rescaled to 350 μm, as a function of the 350 μm flux from Herschel. For the rescaling of the ALMA 1.38 mm flux to 350 μm we use optically thin assumptions with β = 1.75 and the dust temperature from the Herschel SED fitting. The black line is the identity line, and the color scale is proportional to the clump surface Σ, again from Herschel. The vertical black line shows the spread of values that the 350 μm rescaled 1.38 mm flux can assume for different dust temperatures and opacities.
