Median emission profiles integrated within the projected contours of three clumps, numbered 8, 104, and 114 (black curves), and their fit with a multi-Gaussian function (blue curves). Individual Gaussian components of the function are also detailed in red, orange, green, and gray. The noise level of the profile is indicated by a dashed horizontal line. Clump 114 has a smaller angular size than the two others, which explains its higher noise level.
