(from Eq. (2)) versus Ṁ_acc diagram for the extensively mapped outflow sources. The adopted mass-loss rate for Cep E is the sum of both contributions from knot A and the jet; that is, (29.6−60.2)×10⁻⁷ M_⊙ yr⁻¹. In the case of HH 1, we considered the measurement at the HH 1 jet to be the best representation of the instantaneous mass-loss rate. Geometric means for Class 0/I outflows are plotted as non-filled black markers. Error bars in accretion rates are not depicted, but can be of the order of one magnitude.
