Selected multiplets. The bottom 5 panels show the  ~0.13 μHz splitting seen in some of the ℓ = 1 doublets. The strongest pulsations we detect in KIC 11 558 725 are amongst the ℓ = 1 peaks shown here. The top panels show sample regions with sequences of frequencies with splittings in the 0.37–0.58 μHz range. Amplitudes are given in ppm. The significance cut-off amplitude is 17 ppm.
