Extended Data Fig. 6: Identification of other IC related phases.

a–c, Polarization analysis for identification of PKiKP in events S1102a (73.3°), S1153a (84.8°), and S1415a (88.2°) (Extended Data Table 1). The detailed legend follows that of Fig. 2g,h. The black and red dashed lines denote the predicted travel time from BS_SKS_GD_IC model and the measurement by FDPA, respectively. Grey shaded regions indicate the presence of known instrument glitches. d, Vespagram of P′P′r_df using all 23 events, same as Fig. 2a. The red cross denotes the candidate phase. e, Occurrence percentage of grids with high energy in the vespagram for P′P′r_df, same as Fig. 2b. f, Synthetic vespagram of P′P′r_df, based on the inverted BS_SKS_GD_IC model. g–i, Same as in d–f, but for PKIIKP and PcSScP.
