calculated by the B-spline filter and the peak and trough of wave.
| Group | | The peak of wave | The trough of wave |
| The 1st group | 3.729619877 | (36.169,-351.446) | (32.872,-407.965) | The 2nd group | 3.655747609 | (36.17,-351.873) | (32.891,-408.881) | The 3rd group | 3.919482219 | (36.171,-351.934) | (32.924,-409.857) | The 4th group | 3.882077733 | (36.155,-352.789) | (32.922,-409.857) | The 5th group | 3.998053294 | (36.17,-351.995) | (32.894,-409.369) |
