p-mode complex at 4739 μHz. Top: dynamic Fouriertransform computed with a running window of 50 days. The colour cuts range from 0 to 0.08 ppt. Bottom: FT of the full Q06–Q17 Kepler light curve, with the 6 modes that are listed in Table A.3 indicated by green vertical line segments, and the adopted detection threshold by the horizontal line. The typical 0.22−0.24 μHz splitting is indicated for two pairs of these. Twomore such splittings, involving less significant peaks, are indicated in blue. The broad power humps in the full-length FT reflect the short life times of these modes.
