Notes.

^(a)

Uncertainty of 1.1 km s⁻¹ for all three components.

^(b)

Uncertainty of 0.6 km s⁻¹ derived from the residual scatter relative to the model.

^(c)

Uncertainty of 1.1 km s⁻¹ derived from the residual scatter relative to the model.

^(d)

Uncertainty of 0.5 km s⁻¹ from the scatter in the measurements.

^(e)

Uncertainty of 2.5 km s⁻¹ for all three components.
