Combined PdBI and IRAM 30 m integrated emission of H₂CO towards IRAS 19410+2336. In the left panels are the H₂CO(3_0,3−2_0,2) transition in the northern (upper panel) and southern (lower panel) (proto)clusters, and in the right panels of the image are the H₂CO(3_2,2−2_2,1) transition. The contour levels are in 10% steps of the peak integrated intensity for each map. The triangles mark the 1.4 mm sources detected, and the 1.6′′ × 1′′ beam appears in the lower-right corner of each panel.
