Notes. mj denote the component masses, Pj osculating periods, ej eccentricities, ij inclinations, Ωj longitudes of ascending nodes, ωj arguments of pericentres, and Mj mean anomalies. Note P1 is indeed different from Eq. (1), as explained in the main text. The resulting χ2 = 157 756, the total number of measurements Ndata = 21 673. The individual contributions are 
, 
, and 
. Uncertainties were determined by a χ2 mapping, so they correspond to a local minimum.
