INPUT: exactly 100k events from the following runs taken during pp500, minB trigger, tracking attempted only in octant 3.

Attached PDFs are sorted by content, there are 6 pages in each PDF , one per run 

'page001' - overal tracking overview, one sees FGT Z vertex always follows TPC vertex, meaning reco FGT tracks are predominantly primary tracks.

The # of used P & R clsuters for accepted tracks is increasing with the volatge. The # of reco tracks per input events platoes around +200V (at least for this one octant)

'page002,003' show track-cluster residua in both planes , no dependence on HV observed

'page004' - X-Y crossing of reco tracks thrugh 6 discs. Here one sees disc 5 & 6 starts contributing to tracking at larger radii at HV +200V . This is realy good. This makes sense.

'page063' - Cluster total charge (aka adcSum) correlation for clusters used by accepted prim tracks. This is what I was waiting for. Now I claim I do see the MIP peak marching up on the diagonal. In 5 out of 6 discs. Note, there seems to be 2 components: one moving along diagonal, and another with R-charg of 0 moving along +X axis.

'page163' - maxAdc correlation. Gerad - you were partialy right - we were saturated for some (APVs? strips?).  There is always a hot spot in the upper right corner. But there is this 'cloud' moving along diagona as HV grows. So for many reco prim tracks we were not saturated, rather single strip ADC  amplitude was at ADC~300+ped (disc 2) at the 'base' HV. So Niclai was right as well - the majority of pulses we se in the raw plot (JPlot) are not form prim tracks we care about.
