Agenda

1. Announcements
2. Beam monitoring issues
   • New online tool for fitting harpscan data - Richard
     • a blank form
     • a filled example
   • Update on TPOL polarization results from 2016-2017 - Sebastian
   • Verifying systematics for energy deposition cuts in TPOL simulation - pending further work
     • new simulation E vs theta, y-projection
     • original ASU simulation E vs theta, y-projection
