INPUT : 317K minB events from run: 13079078

Method: fit helix to octant 3, cut on Z-vertex <50cm, for used clusters check if there is a R+P pair from  the same disc, increment histo

Definitions:

• adcSum is total charge assigned to given cluster by Anslem's cluster finder   
• maxAdc is computed by my. Each cluster has so called 'centralStrip'. I pick the maxADC out of 7 time bins for this 'centralStrip'

(pedestals were subtracted earlier)
