<div dir="ltr">Hi all,<div><br></div><div>I wanted to pass along these plots generated by Brad Cannon when he was looking at gamma p -> p + gamma gamma K+ K- events in the 2017 data.</div><div><br></div><div>The plots are of the PID confidence levels for the photons both with no timing cut at all, and with a loose timing cut of several ns. I believe that this CL is just based on the timing, so the results suggest that the timing errors used for the FCAL are in the right ballpark, but the BCAL errors need to be updated.</div><div><br></div><div>Cheers,</div><div>Sean</div><div><br><br><div class="gmail_quote"><div dir="ltr">---------- Forwarded message ---------<br>From: Bradford Cannon <<a href="mailto:bcannon@jlab.org">bcannon@jlab.org</a>><br>Date: Wed, Aug 23, 2017 at 2:50 PM<br>Subject: Re: gamma confidence level plots<br>To: Sean Alexander Dobbs <<a href="mailto:s-dobbs@northwestern.edu">s-dobbs@northwestern.edu</a>><br></div><br><br>Sean,<br>
