Notes.

^(a)

LABOCA designation number (from BGH16);

^(b)

From the 2MASS extinction map;

^(c)

In this column we specify if the SABOCA source shows counterparts in the IR, the number of counterparts (or its name if included in BGH16), and their nature: member/not member of B30 (according to BGH16), or unknown (??).
