AuAu 53 GeV - A first look

Executive Summary:
A very first look at the EPD in 53 GeV data. The dN/deta is:

Looking at some "healthy" distributions, there is a weird double peak in the BBC Vz distribution. But I will work on this some more tomorrow:

Analysis
I am using the dNdEta.C written by Mike Lisa for this analysis. I did not comment out any lines or change it, so I think that I may have a slight issue with the mapping because I did not comment out:
AdjustMapping(EpdMaker);

Which will change the hard coding of the mapping. Ok, I will try for another pass.

The MuDsts can be found at:
/star/data09/reco/AuAu54_production_2017/ReversedFullField/dev/2017/
/star/data10/reco/AuAu54_production_2017/ReversedFullField/dev/2017/
/star/data11/reco/AuAu54_production_2017/ReversedFullField/dev/2017/
/star/data12/reco/AuAu54_production_2017/ReversedFullField/dev/2017/

And for the moment, I am running over the st_physics stream with no additional selection criteria. The threshold for "hit/no-hit" is 10, this is something we will want to shortly change.

The plots below are from 5000 events that I ran over using the scheduler. I tried to run over all available files, that might come through in the morning, but I think I needed to break things up into more reasonable chunks.

The mapping is best represented by this picture from Mike:

It has been noted that the TDC does not work in all channels. (The modified QT8 daughter boards, and some channels of the 32B have not been working.)
