Fig. 6 Representation error of each Eigen ray. Asterisks show travel-time difference from ray calculation and black dots show from inverse in left side figure. Light side one shows the difference.

 

4. Conclusion

 

The measurement data of relay transmission is send to JAMSTEC in realtime. Analyze these data and solve time series fluctuation is next step. And this same as another measurement line. For current analysis, exact analysis is after the recovery, but some of analysis is able to do the realtime data.
