Normal échelle diagram for KIC 9467102. The frequencies are folded by the large separation Δν = 10.4278 μHz. The modes that are used in the fitting procedure are marked by the colour symbols: green ‘+’ for m = 1, purple ‘•’ for m = 0, and red ‘-’ for m=-1 modes. The best-fitting results are shown by the horizontal red lines, which connect the components in each triplet. We note that the overlap is serious.
