Color composite image of the region associated with G346.056−0.021 and G346.077−0.056 using IRAC 8.0 μm band (see Sect. 2.2.2; blue), MIPS 24 μm (MIPSGAL Survey; Carey et al. 2009; green), and ATLASGAL 870 μm (see Sect. 2.2.4; red). Positions of the H II regions as listed in Anderson et al. (2011) are shown with the “×” symbols. The “+” symbol shows the position of IRAS 17043−4027. It should be noted here that a few pixels toward the central part of the 24 μm emission associated with G346.077−0.056 are saturated.
