MIR colors for the 37 sources (black crosses) associated with a WISE counterpart out of the total 49 radio sources found toward G358.69+0.03 in this work. The maroon, green, and magenta circles represent the known, candidate, and radio-quiet H II regions, respectively, from the WISE Galactic H II Regions Catalog V2.3 (Anderson et al. 2014). The region above the dashed black line represents the parameter space where all the H II regions and the majority of PNe are present, as identified by Medina et al. (2019).
