Description To constrain velocity gradients below the 410-km discontinuity beneath eastern Asia, we analyzed vertical components of 3 earthquakes recorded in the CEArray. These events have clear triplication waveforms with/without an abnormal X phase. We deconvolved the seismic recordings with their instrumental responses, and Butterworth filtered it from 0.008 to 0.5 Hz. This database is stored in the directories with SAC files as: GRL_Xphase_data/event/station.z, (e.g., ./GRL_Xphase_data/2009_09_03/BAS.z)

Type The vertical-component waveforms are stored with a sampling rate of 20 Hz and a length of 60 sec (20 sec before and 40 sec after the theoretical P arrival time predicted by the reference model IASP91).
Format standard SAC format, can be read directly using sac, Obspy, MATLAB, et al.
