Notes.

^(a)

The value of v₀ in 2008 and 2013 is the average of the result obtained for each of the 4 absorption lines that were measured and the uncertainty is the standard deviation of these measurements.

^(b)

The fitted data here also exclude most values of m₁ near conjunctions which, when plotted on the RV curve, are clearly inconsistent.
