Notes. The number of eclipse times is Ntmin, the number of radial velocity measurements for each star are Nrv,1 and Nrv,2 and the standard deviation of the residuals for each of these data sets are σtmin, σrv,1 and σrv,2, respectively. The contribution of the eclipse times and radial velocity measurements for each star to the total value of χ2 for the least-squares fit are , and , respectively. Other symbols are defined in the text.
