Notes.

(a)

Systemic velocity of the source.

(b)

Distance of the emission peak of the blue/red-shifted lobe compared to the reference position of the hot core. The direction is indicated in parentheses.

(c)

Velocity range adopted to integrate the emission from the blue/red-shifted wing.

(d)

Maximum outflow velocity of the blue/red-shifted wing calculated as the difference between the high end of the velocity range and VLSR.

(e)

Average dynamical time of the outflow, assuming an inclination of 45° (r/Vmax).
