Notes. The first column of each dataset presents the amplitude of the extracted frequencies for the full dataset, while the second column is for the non-periodic-event excluded photometry. Uncertainties on the amplitudes were calculated using Eq. (B.1). All amplitudes are given in parts per thousand. Most of the extracted frequencies are understood to be produced by three frequencies: frot, corresponding to the stellar rotation, fenv, related to the circumstellar environment; and fx, a not-yet-understood frequency.
