From: Complex inner core boundary from frequency characteristics of the reflection coefficients of PKiKP waves observed by Hi-net

Fig. 8

Corrected P wave reflection coefficients at the ICB. P wave reflection coefficients at the ICB as a function of frequency, estimated from PKiKP/PcP spectral ratios (red circles) and noise/PcP (black circles). Ratios are corrected for fluctuations estimated from the P wave reflection coefficients at the CMB, obtained from the PcP/P ratios in Fig. 7. Thin lines are upper and lower bounds by standard errors. Thick lines are theoretical values of the reflection coefficient calculated using ak135 (Kennett et al., 1995). Horizontal arrows indicate the effective frequency ranges. Encircled numbers are explained in Fig. 6
