Ok, collegato a questa modifica bisognerebbe controllare in utils.h il parametro energy_calibration::attpassratio (che dovrebbe essere la frazione di sampling), che una volta era 0.187 mentre ora in sandreco-legacy e':

// active to active + passive
const double attpassratio = 1.;

questo vuol dire che solo l'energia depositata nel mezzo attivo viene considerata nella digitizzazione.
Il valore corretto dovrebbe essere 0.13 per elettroni e fotoni (oppure 0.16 se consideriamo i muoni).
