Light curve and frequency spectrum of five stars assigned to the δ Sct group, illustrating the variety of pulsational behaviour within the group. The left panel shows a portion of the Kepler light curves. The Kepler flux is expressed in ppm, HJD is given in d with respect to HJD₀ = 2   454   950.0. The right panel gives a schematic representation of the detected independent frequencies, expressed in d^-1 (bottom X-axis) or μHz (top X-axis). Amplitudes are given in ppm. The dotted grey line separates the δ Sct and γ Dor regime. Note the different Y-axis scales for each star. a) KIC 8415752; b) KIC 8103917; c) KIC10717871; d) KIC 9845907; e) KIC 9306095.
