Mass accretion (Ṁ_acc) vs. mass ejection (Ṁ_jet) rates. The mass ejection has been measured from the [O i]6300 Å  luminosity assuming a jet tangential velocity of 100 km s^-1  and gas temperature and density of 10 000 K and 5 × 10⁴ cm^-3  respectively. Black, red and green symbols are as in Fig. 4, while blue triangles indicate the values for the sample of Taurus sources of H95. Updated mass accretion rates from these sources are estimated from the data in Rigliaco et al. (2013). Average data point uncertainty is indicated with a cross on the left side of the plot. Arrows refer to upper limits on Ṁ_jet  derived from the 3σ upper limits on the L_{[O i] HVC} luminosity.
