Correction to minutes:

On sector 24 -rdo 4. Tim has upped the Power voltage a bit on RDO 24-4 
(itpc),
Tonko will test it with pulser runs. It was us/I who asked tim to look 
at it, since fast offline found the problem during the auau run.

Isaac  wrote part of the TPC fast offline QA 2 years back. I want to fix 
some mistakes, and add some histograms. Gene is helping me with the 
github procedure needed, and scripts needed to test these.
I am working to further automate the QA done during the run.
