Consecutive frequency differences (KIC 11244118); that is, the separations between the fitted peaks for NAvPSD. Two levels are shown: one around Δν/ 2, corresponding to p-modes (blue dashed line with a weighted mean of 35.54 ± 0.08 μHz), and other around Δν, corresponding to pseudo-modes (blue dotted line with a weighted mean of 61.02 ± 2.19 μHz). The red symbol is the estimation of the acoustic cut-off frequency (1968.69 ± 21.48 μHz).
