Notes. Where two errorbars are given, the first refers to the statistical uncertainties and the second to the systematic errors.
This value of KA was determined from our RV data, which were taken during transit time only. The value reported by Bakos et al. (2009), which is based on RV data with a much better coverage of the orbital phase, was therefore preferred for the determination of the other physical parameters of the system (see Sect. 5).
