a Actual LSR velocities; note that the quiescent gas is at $V_{\rm LSR}=5.3$ km s-1. $\delta V_{\max}$ = abs( $V_{\max}- V_{\rm {LSR}}$). Velocities are not corrected for inclination.
b Corrected for inclination using the average correction factors of Cabrit & Bertout (1990).
c Constant temperature of 100 K assumed for red outflow and 70 K for blue outflow.
d Dynamical time scale: $t_{\rm {d}}=R/\delta V_{\max}$.
e Mass outflow rate: $\dot{M}=M/t_{\rm d}$, not corrected for swept-up gas.
f Outflow force: $F_{\rm CO}=MV_{\max}^2/R$.
g Kinetic luminosity: $L_{\rm {kin}}=0.5M(\delta V_{\rm {max}})^3/R$.
h 0.8 $M_\odot$ is derived for a temperature of 50 K. 2.9 $M_\odot$ is derived for a temperature of 100 K.
i Outflow extends to far larger scales than map scale.
