Notes. As a first guess of the period, we used that corresponding to the Fourier periodogram peak, and then refinement was performed, if needed, within LOSP. These solutions are tentative since the temporal coverage of the period is not satisfactory. Thus, intensive monitoring over at least one full period is needed to ascertain these orbital solutions. T0 stands for the time of passage at periastron when e ≠ 0 and at conjunction (primary in front) otherwise.
