Notes. RVs are estimated by performing a second-order polynomial fit to the peak of the CCFs. F21 represents the secondary-to-primary flux ratio, F2/F1, given by the ratio of the peaks of the cross-correlation functions of the secondary (F2) and primary (F1) component. The error of this measurement is given by eF21.

^(a)

Heliocentric Julian day.

^(b)

Radial velocity of the primary.

^(c)

Radial velocity of the secondary.

^(d)

Discarded RV point during the RV fitting procedure.
