	*		*Further analysis of November test beam data, discussed in this presentation.
			**Compared November photodiode data to April CMOS data:
			***Observed consistent discrepancy in build-up to Bragg peak causing poor fits with photodiodes.
			***WET seems to be consistent across data sets.
			**Fitting data around peak does not improve things.
			**Reverse engineered fit using fixed "correct" values of range and sigma, and varying only Birks' and phi.
			***Observe large differences in Birks' constant across data sets, photodiode fits remain worse.
			*Will perform fits with CMOS data, taking only central stripe.
			**Simon to provide WET calibration value for fitting Nikon data from November.
			*Discussed potential causes of poor fits with Laurent:
			**Could be that scintillator sheets are damaged after stripping and repainting.
			**Overarching problem of detector is non-uniform light output, dependant on beam position and light sensor position/size. Photodiodes could be missing dose.
			**Doing a test with mylar foil wrapping could be useful – especially with new sheets from Nuvia and Rev. C DDC232 boards.
			*FPGA programming:
			**Nexys Video design ready for testing with Rev. C hardware.
			**Ported PMOD design to USB104, will test and debug.
			**Will debug Matt's fix for signals crossing clock domains.
			*First draft of FRPT presentation, small changes to videos/images required.
