Types of matched cores Matching criteria Number of associated stellar objects Number of cores containing stellar objects


With IR objects With YSOs With YSO candidates Contain IR objects Contain YSOs Contain YSO candidates
672 observed cores ~2′ 131 (~19%) 57 (~8%) 58 (~8%) 112 (~17%) 29 (~4%) 23 (~3%)
249 NH3 detected cores ~2′ 66 (~27%) 48 (~19%) 52 (~21%) 53 (~21%) 23 (~9%) 17 (~7%)

Notes. Matching criteria refer to associated objects within the ~2′ ammonia beam size.
