a Taken from the proper motion study by Bally et al. (2002). Total velocities ( $v_{{\rm jet}}$) have been derived from these values assuming an inclination angle of 10$^{\circ}$.
b Taken from the FWHM intensity transverse profiles in HST images of Reipurth et al. (2000).
c $\dot{M}$( $n_{\rm H},r_{\rm j},v_{\rm j}$) = $\mu~m_{\rm H}~n_{\rm H}$ $\times $ $\pi~r_{{\rm jet}}^2~v_{{\rm jet}}$, where $n_{\rm H}$ is the total density reported in Table 2. Volume filling factors equal to unity are assumed.
d $\dot{M}$ measured from the luminosities of the [S II]$\lambda $$\lambda $ 6716, 6731 lines and [Fe II]1.64 $\mu $m line.
e Volume filling factor estimated from the ratio between the observed and predicted line luminosities (see text). They are also equal to the ratio between $\dot{M}$ and $\dot{M}$( $n_{\rm H},r_{\rm j},v_{\rm j}$) derived from line luminosities.
f $\dot{M}$ measured from the luminosity of the H2 2.12 $\mu $m line, assuming the H2 temperature estimated from the ratio of the different H2 observed lines.
