Notes. 

(a)

Obtained from Gaussian fits to each component. All Gauss-fit parameters are provided in Table 2.

(b)

Measured in 1 km s-1 bins.

(c)

Obtained by fixing the position and width of Gaussian functions and only fitting the intensity.

(d)

Upper limits are 3σ.

(e)

Intensity-weighted average of values determined from Gaussian fits to the H2O lines. Uncertainties include statistical errors only.
