Hi,

I was looking at some newly cooked data and am getting results for beta 
vs. momentum that look strange.

The plot for the newly cooked data ->

A plot of the previous version of cooked data ->
http://www.jlab.org/Hall-B/secure/g8b/ASU/tmp/OldBetaVsP.gif

The plots are from PERP, 1.5 GeV, run 48483. The new plot only contains 
events from file A01.B02, while the plot of the previous cook has all A01 
files.

The resolution looks much better, but we now have and extra stripe below 
the proton, and the stripe below the pions is crossing the kaons more 
heavily.

Is anyone else seeing this sort of behavior?

Take care,
Michael
