SPani_dvp.nc                                          PREM; "SPani_vp.nc" stores repeated infomation.
HMSL-P06_dvp.nc                                       AK135; "HMSL-P06_vp.nc" is calculated from "HMSL-P06_dvp.nc" and AK135, but the paper mentioned the dvp may not suitable for travel time calculation.
MITP08_dvp.nc                                         AK135; "MITP08_vp.nc" is calculated from "MITP08_dvp.nc" and AK135.
LLNL-G3Dv3_dvp.nc                                     Layer mean; Use "LLNL-G3Dv3_vp.nc" to obtain dvp reference to PREM.
GAP_P4_dvp.nc                                         ? (raw data is in %, may need to ask the authors, or read the paper more carefully)

HMSL-P06_dvs.nc                                       AK135; "HMSL-P06_vs.nc" is calculated from "HMSL-P06_dvs.nc" and AK135, but the paper mentioned the dvs may not suitable for travel time calculation.
SEMUCB-WM1_dvs.nc                                     model.ref in downloaded package; "SEMUCB-WM1_vs.nc" is calculated as Voigt-average of "SEMUCB-WM1_vsh.nc" and "SEMUCB-WM1_vsv.nc".
TX2000_dvs.nc                                         An average model (TNA and SNA for the upper mantle and PREM for the lower mantle.)
TX2011_dvs.nc                                         TX2011_ref; "TX2011_vs.nc" is calculated from "TX2011_dvs.nc" and TX2011_ref. But I'm not sure about the "layer mean removed" description.
