Notes. Results from Mohler-Fischer et al. (2013) are also reported for comparison. Where two error bars are given, the first refers to the statistical uncertainties, while the second to the systematic errors. Other derived parameters, i.e. the stellar rotational period, the sky-projected obliquity, the inclination angle of the stellar spin, and the true obliquity are also listed.
