⁽¹⁾ Observed characteristic offset velocity of the outflow lobe (see details in Sect. 4.2), computed over the [V₁; ${V_{\rm sys}}$ ] velocity range.
⁽²⁾ Length of each outflow lobe.
⁽³⁾ Dynamical timescale of each outflow.
⁽⁴⁾ Minimum and maximum masses of outflow-entrained gas, computed as explained in Sect. 4.1.
⁽⁵⁾ Minimum and maximum momenta, computed as explained in Sect. 4.2.
⁽⁶⁾ Range of momentum flux derived for each outflow (see Sect. 4.2).
⁽⁷⁾ The last two rows give, for the sake of comparison, the values computed for the two bipolar outflows L1551 and L1157, used by Nakamura & Li (2007).
