Notes: "SpT": Approximate spectral classification from photometric data (see Sect. 3.2.1 for details).
"Obj. type": Adopted object nature from our photometric analysis (see Sect. 4.3 for details).
"Notes": "Gaia" indicates objects with GAIA EDR3 information. In particular, an asterisk indicates those probable astrometric cluster members detailed in Table C.2. Obj1, Obj2 and Obj3 indicate the particular objects described in Sect. 4.3 and shown in Fig. 10. C1/C2 indicate objects located at radio source G316.8−0.1−A peak and probably associated, respectively, with C1/C2 molecular clumps identified by Samal et al. (2018).
