Results of using a modified version of an analysis method developed for solar-like oscillations observed with Kepler, as described in the text. Upper panel: results based on the SONG power spectrum. Middle panel: results for K2. As in Fig 4, the dashed lines in the upper panel indicate signals originating from the 1 d⁻¹ aliases in the spectral window, and the arrow indicates the Δν-value of 5.0 μHz. Bottom panel: SONG and K2 results from the two upper panels are multiplied, resulting in a very clear peak near 5.0 μHz.
