Hi Gregg,<br><br> Here is a 2d plot of the energy vs momentum for a few of our positive polarity runs, looking at positrons (bend-up particles in the BigBite for positive polarity). This plot has all of our cuts applied except for the E/p cut. This looks very much like our negative polarity E vs p plots.<br>

Matt,<br>
Diana's E vs P plots for electrons turned out to be pretty<br>
interesting. They tell a slightly different story than the 1D E/p<br>
histos. Have you looked at a E vs P 2D histo for the reverse running<br>
positrons? (We're still working on trying to understand the background<br>
in Diana's analysis that seems to be associated with miss-assigned momenta.)<br>
