Notes. We give the values of the mode and 1σ confidence interval of the posterior distribution from the MCMC. (†) The linear parameter was adjusted on 
smoothed with an Epanechnikov kernel with a 1.5 yr timescale. (‡) Eccentricity does not differ significantly from zero; the 68 and 95% upper limits are reported. The argument of periastron ω is therefore unconstrained.
