Notes. 

(a)

Integrated line intensities measured from the images presented in Fig. 2. I [FeII]  and IH2S(1) are not corrected for extinction. Intensities are integrated across the entire extent of the observed jet in each object.

(b)

Extinction, Av. For each source the median of values measured from H2 and [Fe ii] line ratios and/or H2 rotational excitation diagrams (listed in Table 6) is used. If these are not available, the extinction measured from the colour–colour diagram is employed.

(c)

H2 and [Fe ii] flow component radial velocities, uncorrected for flow orientation (see Table 2 in Davis et al. 2003, for details). Two equally strong peaks are detected in the H2 echelle spectrum of HH 72-IRS – the range in values above takes into account these two velocities. For HH 999-IRS we use canonical values, based on the other sources in this table (data are marked with a ∗); the HH 26-IRS H2 velocity is taken from Antoniucci et al. (2008).

(d)

Mass outflow rate and momentum flux in each flow component, derived using the velocities list in Cols. 5 and 6, corrected for the flow orientation angle listed in Tables 2 and 3. All values are also corrected for the extinction, Av, listed in Col. 4 above.
