Notes. Circular orbit was assumed and the period was kept fixed at 33
773 d. The solutions were derived using three different RV sets based on the KOREL template spectra for the optimal mass ratio q of 9.75, and for two other plausible mass ratios 7, and 16. The epoch of the superior conjunction Tsuper. c. is in RJD−55487 and rms is the rms error of 1 measurement of unit weight. We note that due to the use of the KOREL template spectra, the asTODCOR RVs are referred to zero systemic velocity.
