- Update in Mar. 6:

Below are instructions for installing and running FastJet on RCF.

 

 

 

 

 

The first EPD timing scan took a good part of the weekend of 23-24 Feb 2019, due to poor beam availability.  But unfortunately the QT32B algorithm had a corrupting bug.

 

All runs had:
QTC TAC_Max 2900
QTC_TAC_Min 300
TACdiff_max 4720
TACdiff_min 3470
EWdiff_max 163
EWdiff_min 93

 

To help (or not) to clarify discussions we're having about how to best interpret timing curves, for instance in EPD, I made a very trivial toy model in Mathematica.
