C7 clump. a) Colour composite image with the 24 μm, the 8.0 μm, and the 3.6 μm emissions, respectively in red, green, and blue (linear units). Two candidate Class I YSOs, #14 and #15, are identified; the brightness of YSO #14 has been enhanced. The three blue arrows point to candidate AGB stars. The red contours are for the column density (same levels as in Fig. 21b). b) The column density contours are superimposed on the MAGPIS radio map at 20-cm. The UC and compact H ii regions are identified, which have 24 μm and 70 μm counterparts.
