Notes. (1) Grouping based on the detection at 70 and 24 μm and presence of counterparts, as discussed in Sect. 2.7: A1 = Detection at 70 and 24 μm; A2 = detection at 70 and upper limit at 24 μm; B1 = upper limit at 70 μm and detection at 24 μm; C1 = no data at 70 μm and detection at 24 μm. Objects without detected emision at 24 and/or 70 μm are not listed here (B2 and C2). Tentative classification: YSO = Young Stellar Object, with a optical and/or nearIR sources within 5 arcsec of APEX/LABOCA central coordinate. Our tentative interpretation is that most of them are proto-stars or proto-BDs. Excess = Optical and/or nearIR sources with excesses within the APEX/LABOCA beam but farther than 5 arcsec. The submm source cannot be assigned unambiguously to any counterpart so its nature remains unknown. Starless = Possible starless core, since there is neither counterparts closer than 5 arcsec nor a optical/IR source farther away with excess. (2) Including the flux at 870 μm from APEX/LABOCA and, if present, MIPS M2. (3) Internal luminosity, based on MIPS flux at 70 μm, after Dunham et al. (2008). (4) SED classification based on the Tbol versus Lbol diagram. (5) There is a submm source nearby, namely SB08, detected with APEX/SABOCA at 350 μm (Huélamo et al. 2017). (6) There is a submm source nearby, namely SB05, detected with APEX/SABOCA at 350 μm (Huélamo et al. 2017). (7) There is a submm source nearby, namely SB04, detected with APEX/SABOCA at 350 μm (Huélamo et al. 2017). (8) There is a submm source nearby, namely SB03, detected with APEX/SABOCA at 350 μm (Huélamo et al. 2017). (†) Membership status updated from Table 7 to Y? based on all the available data and our analysis. (*) Possible detection at MIPS 24 μm, but if real, it might be affected by the inhomogeneous extended emission by the nebulosity.
