enum | { nWeightsRows = 3, iAmplitude = 0, iPedestal = 1, iTime = 2 } |
Template used to compute amplitude, pedestal, time jitter, chi2 of a pulse using an analytical function fit, with the pulse parameters alpha and beta fixed. It follows a fast fit algorithms devolped on test beam data by P. Jarry If the pedestal is not given, it is calculated from the first 2 pre-samples; FIXME: conversion gainID (1,2,3) with gain factor (12,6,1) is hardcoded here !

fit electronic function from simulation parameters fAlpha_ and fBeta_ are fixed and fit is providing the 3 following parameters the maximum amplitude ( fAmp_max_ ) the time of the maximum ( fTim_max_)
Loop on iterations
initialization inside iteration loop !
Then we loop on samples to be fitted
calculate function to be fitted
then calculate derivatives of function to be fitted
compute matrix elements DM1
compute delta
compute vector elements PROD
end of loop on samples
compute variations of parameters fAmp_max and fTim_max
end of loop on iterations
protection again diverging/unstable fit
results of the fit are calculated
