Continuum emission toward Sgr B2(M) at 242 GHz. A close-up of the central part is presented in the right panel. The identified sources are shown as blue shaded polygons and are labeled with the corresponding source ID. The black points indicate the position of each core, described by Sánchez-Monge et al. (2017). The intensity color scale is shown in units of brightness temperature, and the synthesized beam of 0.″4 is in the lower left corner. The green ellipses are the H II regions identified by De Pree et al. (2015).
