3. Yelena talked about using Compton for energy calibration and showed
   plots for both double and single arm Compton. She did separate
   calibrations for low and high beam energies for double arm and
   found that more crystals can be covered with lower energies. For
   the non-linearity issue she compared the gain corrections from the
   low and high energy samples.She will make available in database 6
   sets of Compton gains to be used as an option to snake scan
   gains. She showed that a Compton peak can be identified in
   production runs for single arm Compton. Peak can be used to
   calculate gains for those runs. Links are below.
