Notes. The envelope mass of the protostars are taken from Li et al. (2013) and Takahashi et al. (2008). The data for the radio component are taken from VLA cm-radio emission (Reipurth et al. 1999). The data on the outflows are from Takahashi et al. (2008). (a) Left out of the analysis due to prominent non-Gaussian line wings. (b)Data from the 3mm only, as there was emission contamination from the wobbler off position for the 1mm data set.
