Matching results by types of stellar objects.

Types of matched cores	Matching criteria	Single-source matches			Multi-source matches

		IR	YSO	YSO candidate	YSOs and YSO candidate	IR and YSOs	IR and IR and YSOs and YSO YSO candidate candidate
672 observed cores	~2′	102 (~15%)	18 (~3%)	16 (~2%)	4(~1%)	7 (~1%)	3 (~1%)
249 NH₃ detected cores	~2′	45 (~18%)	13 (~5%)	9 (~4%)	5 (~2%)	5 (~2%)	3 (~1%)

Notes. “Single-source matches” are sources that are exclusively associated with either an IR source or with one specific type of stellar object. “Multi-source matches” refer to sources that are associated with multiple types.
