Notes. (a)Mid-IR spectroscopic classifications in An et al. (2011). The non-YSO classification primarily reflects the weak or absent absorption of the CO2 shoulder component, but does not necessarily rule out the possibility that the source is a YSO envelope or a dense core at an early evolutionary stage.
