I have started to write a macro to go from ’MakeMmixPi0.C’
to Production.
I have used the output from ’MakeMmixPi0.C’ as it is on
repo.
I
Take note that i have made some changes to this macro over
the last couple of months, though these changes are just
safeguards, they should not change behavior.
I
I have used GA_PbPb_output_8/
I
All errors are those calculated in ’MakeMmixPi0.C’
propagated by TH1::Scale and TH1::Divide
2/7
I have made two types of plots, “Raw Production” and
“production”
Raw Production is
I
output of ’MakeMmixPi0.C’ simply normalized by dpt pt
Production is
I
additional normalization by 2π, and
I
efficiency correction.
Macro not currently on reop, will add after a little cleanup.

I efficiency functions sent to me by Dmitri has discrepancy in
