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