Detailed Description

Compute trk efficiency at DE, chamber, station and spectro levels vs various variables from the output of the efficiency task.

Author

Philippe Pillot, Antoine Lardeux, Lizardo Valencia Palomo, Javier Martin Blanco 1) efficiency estimator and error calculation at chamber and DE level: 2 options:

using bayesian method with uniform prior
using Clopper-Pearson or other frequentist method if n ≠ 0: use above methods if n = 0: eff = -1 ± 0

2) efficiency and error propagation at station and spectrometer level: if eff = -1 for one or several ch/DE:

assume eff_ch = 1 ± 0 to compute eff_up and err_up with std error propagation at nth order
assume eff_ch = 0 ± 0 to compute eff_low and err_low with std error propagation at nth order
eff_spectro = eff_up + err_up - (eff_up-eff_low + err_low) otherwise: std efficiency and error propagation at nth order

3) efficiency and error integration over runs

performed from efficiency plots versus run
compute weighted average and apply standard error propagation to err_up and err_low
do it for both extreme cases above (with eff_up ± err–up and eff_low ± err_low)
int_eff = int_eff_up + int_err_up - (int_eff_up-int_eff_low + int_err_low)
