Notes. 

(a)

Orientation of the jet or outflow with respect to the line of sight.

(b)

Values are derived from the multi-component Gaussian fits to the profiles shown in Fig. 3. Note that these parameters are limited by the seeing (which has not been deconvolved from these data) and, in some cases (notably Brγ), the features may be unresolved. Values on sky, given in arcseconds and in AU (using the adopted distances listed in Table 1), are uncorrected for flow orientation; Values along the jet axis have been corrected for the flow inclination angle, α.
