=Minutes=

* Meeting scheduling: expand the poll
* Copying files to JLab: instead of /volatile (over quota) copy to /work disk
* Beam generator simulations (Raj)
** same geometry as Elham (rotated and shifted showermax)
** factor 10 larger rate from beam generator than from Moller only
** TODO: compare difference between rates when shifting detector with what Elham sees as difference
* Bayesian extraction (Julie)
** final distributions are reproducing priors, but around zero mean values
** multiple chains and longer chains not resulting in the advantages hoped for
** looking at code, maybe the dilution factor not applied as intended?
* Updates on pion detector studies (Elham)
** maybe seeing photon rings?
** maybe not seeing photons on upstream face because of incorrect z?
** TODO: look up number of photons generated per unit length
** can put PMTs sideways on lucite, behind lead donut
* What's next?
** Look at optical photon vx,vy,vz locations
** Compared Moller events with pion events in terms of number of generated photons
** Set up standalone optical simulations again
