[Halld-tracking-hw] CDC dE/dx with track angle

Wow!
I start to become a converter! APMLITUDE ROCKS!
It looks like flash ADCs with "firmware" do behave in different ways!

cheers,
Beni

Hi, 

Below are plots of CDC dE/dx vs theta for conventional dE/dx (left) and dE/dx from peak height (right). 

Rather than fight through the reaction channel analysis to pick out a specific particle type, I used all time-based tracks and selected those which have at least 3 hits with z between 50 and 80cm in the innermost 4 rings of straws. This is from run 31001. 

Have a great weekend, 

Naomi.
