Things to do regarding last project

1, for the zero momentum surface - I'd better do the sampling on two leaves separately.
2, for the high density along orbits - I don't think wavepacket is sufficient to explain everything (the 2nd-order approximation is very inaccurate, and base everything on an expansion-contraction balance sounds shaky to me). I think some diffusion argument can be made - so we know how to calculate the relative intensity.
3, for the fraction of regular trajectories - that result should be double-checked. I need to look into the high energy limits, and plot a few fLI vs. time to see if it is logrithmatic or linear. If no concrete results can be found, I will drop it.
