Notes. We indicate the frequency and corresponding amplitude, A, together with their respective uncertainties, as well as the S/N of the detection in the Lomb-Scargle periodogram during the iterative prewhitening procedure. The frequency and amplitude uncertainties are determined from Montgomery & O’Donoghue (1999), under the assumption of white noise and uncorrelated data. These conditions are not always fullfilled and result in a typical underestimation of the frequency error by a factor 10 (e.g., Degroote et al. 2009b). We also indicate the proposed origin of the observed periodic photometric variability and remark that a more precise value for the rotation period was obtained through the magnetometric analysis in Sect. 5.
