There are two gaussian smearings, one before the discriminator and one after. 11 F Width of noise before discriminator in ADC counts 12 F Width of smearing before discriminator in ADC counts Below are parameters for simulated high-half point distribution (if the true high-half point is not selected---see MCMA bank). The distribution of high-half points is approximated by a gaussian. 13 F Mean of high-half point distribution 14 F Width of high-half point distribution Below are parameters used for simulating thresholds (as opposed to using the thresholds recorded in the DQXX banks). 15 F Mean of simulated threshold distribution or fixed uniform threshold 16 F Width of simulated threshold distribution
