Visualization of adopted conventions for outflow velocity and outflow CO flux. vout = |Δv|+FW10%/2 (Eq. (1)) is derived from the shift of the broad Gaussian outflow component with respect to systemic velocity and its full width at a tenth of its peak. SCO (gauss) is the integral of this broad component. The flux in the wings of the broad component SCO (wings), indicated by the blue shaded area, integrates the broad component only over the velocity ranges for which it contributes at least 50% of the total flux density of the line.
