[Hps-analysis] followup on track pulls

[Nelson, Timothy Knight]

What I mean to say is…

- There is an apparent difference in the tails. Broader bins in the pull would help, since stats are pretty limited in these 1-d plots
- It wasn’t obvious that this difference in the tails didn’t also mean the core of the distribution wasn’t also different. Thanks for showing that it’s not.

Still… why the difference in the tails?  These tails are too big to be from single scatters.  Hit mis-assignment?
