Agenda

1. CREX AT runs update: Weibin & Robert haplog4120
   • WZ: for the dpp i have the mean and RMS
   • KK: it's important to see the tails (5-10 sigma away) and log plots
   • KK: for the narrow peak we should look into detail (vs event number)
   • Ryan: started looking at the form factors. At 2GeV the C fraction is much larger than at 1GeV. 4.2MHz for C and 13.6MHz for Pb. Still cross checking the form factors. DA: Using a different technique, I get 2.23 ration of C/Pb (will upload calculation). These are different things and Devi and Ryan will work through it.
   • CG: we should get some dithering results for these runs as well.
2. PREX2 AT runs update: Ryan haplog4119
   • Ryan: still need to recover what the raster size is.
   • CG: we should confirm 4120, 4121 was hitting the frame. Ryan: will do
   • Ryan: will work on getting more detailed plots (similar to what Weibin has)
   • KK: we should double check why the difference in the error bar to the average between the dithering and regression. Ryan: will work on plots (maybe vs minirun). KK: the dithering mostly likely will need work (together with the dithering experts). Ryan: will work with Devi
3. PREX1 AT systematics summary: Ciprian
   • next time
