a) Map of the continuum emission at 3.6 cm (black contours; from S2010) overlaid on an 8.0 μm image (resolution 2′′) of the G16.59−0.05 region from the GLIMPSE/Spitzer survey (Benjamin et al. 2003). b) Same as panel a), for our Subaru 24.5 μm image smoothed to the same angular resolution as the 8.0 μm image (2′′). c) Same as panel a), for the Hi-GAL/Herschel (Molinari et al. 2010b) 70 μm image (resolution ~10′′). The white dots indicate the positions of the centimeter sources “a” (alias mm-core), “b” (alias HMC) and “c” detected by Zapata et al. (2006).
