[Halld-tracking-hw] CDC dE/dx and truncation

[Naomi Jarvis]

The attached files each have a few plots in comparing runs at different rates and changing the dE/dx truncation from 50% to 20% (this is the % of hits which are removed, starting with those with largest dE/dx).


My observations:

The dE/dx from pulse integral broadens at higher rates, quite a bit more than the dE/dx from amplitude does.

Changing the truncation to 20% is very beneficial to the dE/dx from integral, only slightly beneficial to dE/dx from amplitude (the 20% was picked for optimal dE/dx from integral).

dE/dx from amplitude gives better separation than integral, even with 20% truncation.  Maybe this would improve further with a different %. 


Best,

Naomi.
