It's hard to imagine what some of those lines mean.

Also, a hint from high-school trig, acceleration is the derivative of velocity, and thus should have its peaks at different times (i.e., peaks phase should be shifted by 90 degrees).

By visual examination, the "Earth acceleration" line is NOT the time derivative of the "Earth velocity" line, and "Changes in Earth acceleration" is NOT the time derivative of "Earth acceleration".
