Hα (red), GLIMPSE-8 μm (green), and SIMBA-1.2 mm (blue) composite image of NGC 6334 (upper panel) and NGC 6357 (lower panel). The quoted coordinates are galactic coordinates. The overlaid isocontours are from SGPS radio emission. The purple and cyan circles show the H ii regions from Anderson et al. (2014) and Langston et al. (2000) respectively. For NGC 6357, the position of stellar clusters Pismis 24 (red diamond) and AH03J1725-34.4 (blue diamond) are also indicated.
