Notes. From left to right, the columns are (1) sources name; (2) right ascension of 1.2 mm; (3) declination of 1.2 mm; (4) radio source near the detected source; (5) right ascension of cm wave continuum emission; (6) declination of cm wave continuum emission; (7) information for 8 μm; (8) information for cm wave continuum emission; (9) positional comparison between CM/MM sources; (10) evolutionary stage of single core. The D, S, and “−” in Col. (7) indicate dark object, point-like sources and objects that are neither point-like source nor dark spot. The W, S, and N in Col. (8) signify that the cm wave continuum emission is weak, strong, and no emission.
