250 μm cold dust emission contours superimposed on the 250 μm image. The image is centered at α₂₀₀₀ = 19^h49^m16^s, δ₂₀₀₀ = + 26°49′39′′. The contour levels are in the range from 980 MJy sr^-1 to 3000 MJy sr^-1 at intervals of 199 MJy sr^-1. North is up and east is to the left. The clumps discussed in the text are labeled C1 to C9. The yellow ellipses are the apertures used to integrate the 250 μm fluxes.
