Altro 3 vs. Altro 4 - dEdx ADC Correction

Updated on Thu, 2019-09-26 13:10. Originally created by iraklic on 2015-08-06 10:49.

ADC to dEdx correction for two different Altro thresholds are compared. Resultant effects on dEdx resolutions are shown as well.

The correction factors are extracted for both cases:

Altro_thr = 3
Altro_thr = 4
Above plots show simulated vs. reconstructed ADC for both altro threshold cases.

The new correction parameters are then used to simulate Altro thr = 4 MC sample. dE/dx resolution comparison plot is shown below:

(Note: Fit done by - root4star -q -b lBichsel.C <filename> 'dEdxFit.C+("<histogram>", "GP")')
