HVG degree distributions of three HADS light curves (HD 146953, PT Com, V1384 Tau) in the left column and three LADS light curves (TIC 329153513, TIC 348772511, and TIC 459908110) in the right column. These distributions are shown in the context of all frequencies (green), in absence of the dominant frequency (blue), and in the absence of all significant frequencies (red). The black dashed line shows the theoretical expression for random series (see Eq. (6)). The KS_D is presented for these three stages of pre-whitening for each star. Note: it is getting smaller and quite close to the value of 0.0040 ± 0.0014.
