Light curves and frequency spectra

<p>The light curve, wavelet transform, and frequency spectra analysis of each stars in our sample. The upper panel displays the light curves of the star, with it&rsquo;s EPIC identifier. The middle panel shows the wavelet transform of the light curves. The lower panel presents the frequency spectra of the stars, with the blue line indicating the frequencies obtained using the cleanest method and triangles indicating the frequencies found with the ivs-KULeuven iterative prewhitening routine (Degroote et al. 2009). Each star is identified by its EPIC number.</p>
