Like Fig. 2, but for StHα166. In the middle panel, instead of the overall wavelet power spectrum, the average power spectrum during more variable phases (t< 700 and 900 <t< 1500) is shown in as a solid line, during less variable (700 <t< 900 and t> 1500) as a dashed one. The label Š denotes the circumstellar Štefl frequencies (see Sect. 4.2).
