Spatial distribution of CH₃CONH₂-detected sources projected onto a schematic top-down view of the Milky Way. Cyan symbols represent sources with CH₃CONH₂ detections in this work, red symbols sources where CH₃CONH₂ was not detected, and orange symbols previously reported detections from other studies. Notably, IRAS 17175 MM1/MM2 (this work) and NGC 6334I MM1/MM2 (Ligterink et al. 2020) are actually the same HMCs and are therefore shown exclusively with cyan symbols.
