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

Compute the mean and the RMS of the t0 from the maps and write them to the DB with channel granularity.

Loop on superlayer to correct between even-odd layers (2 different test pulse lines!)

Change t0 absolute reference -> from sector peak to chamber average

Write the t0 map into DB
