Scintillator working point optimization (efficiency for m.i.p.)

Root macro for efficiency plateau fit
Use it in root (tested on Version 5.32/00) with
.x fitPlateau_showRate.C("1atLS1_doppie_LS3_LS7")
to use input data in a file named hv_plateau_scint_1atLS1_doppie_LS3_LS7.dat with content as in the example below. Look here at the result.
For root version 6 (and previous) use this.

Example of input data for efficiency plateau fit hv_plateau_scint_1atLS1_doppie_LS3_LS7.dat
Each row contains:
HV (in kV), n. of reference events, n. of successes, total n. of counts of the device under test, time span of the measurement (in s).

PMT calibration: single photo-electron spectrum and absolute gain vs HV determination
