Selected regions in Fourier space where large multiplets occur, indicative of ℓ> 2. The Fourier amplitudes are given in units of ppt; the red line reflects our adopted detection limit. For each apparent sequence of modes, a grid of vertical lines is drawn with an indicated average splitting based on the frequencies of the first and last clear mode in the sequence. The bottom panel shows either a chance alignment of an ℓ = 2 and an ℓ = 3 multiplet, or a single multiplet of ℓ ≥ 6. The 802−805 μHz structure could be an ℓ ≥ 6 multiplet. The 1002−1004 μHz structure could be an ℓ ≥ 5 multiplet. For the 1039−1043 μHz structure, which is consistent with an ℓ ≥ 8 multiplet, the dynamic Fourier transform as a function of time is shown; for this a sliding window of 200 days was used. Note that all frequency splittings of these ℓ> 2 modes are very similar in value.
