[d2n-analysis-talk] Beta distribution

[David Flay]

Hey Brad,

I've been tweaking the S1 average times for each paddle, and it turns out
that that shoulder on beta seems to be highly correlated to the 4th and
5th paddles (3rd and 4th indices if we start from 0).  Attached are the
some characteristic plots.

I think beta has improved, but I'm not sure how much more I can do to get
the shoulder to fully go away.  If you look at my previous plots of beta,
you'll see <now> that the higher end of beta decays much smoother (in
fact, it almost perfectly matches an exponential decay).  There are still
some blips in beta vs. track-x, however.

So, I think this is a step in the right direction.  If you look at the S1
time avg. vs. track-x and, in particular, S1 time avg. vs. paddle number,
I don't know if there's too much more room to move in adjusting those
times for paddles 4 and 5.

What do you think?

Thanks,

Dave
