Detailed Description

Analyzer class computes the mean and RMS of t0 from pulses. Those values are written in the DB with cell granularity. The mean value for each channel is normalized to a reference time common to all the sector. The t0 of wires in odd layers are corrected for the relative difference between odd and even layers
