- Simulation (mcsmear)
- fADC timing
- Uses threshold crossing time rather than FPGA-ish algorithm
- Resolution is too poor
- mcsmear doesn't seem to smear data enough
- TDC timing resolution is too good
- single photo-electron peaks in energy spectrum
- spikes in time histogram at low energy
- max ADC amplitude (12 bits?)
- Sampling fluctuations not applied on per-particle basis
- fADC timing
- Timewalk corrections
- Establish procedure for doing these corrections based on simulated data (how closely should this match the correction procedure for real data?)
- Determine form of timewalk corrections
- What if we have TDC info only on one end?
