Description

This is data back from 2015. I was never totally happy with how I processed the data originally. I have been taking stabs at reprocessing this data since 2015 but never really got anywhere. I finally decided to buckle down over the past few months to get what you see here.

I am still not totally satisfied, but that is mainly a fault of the data rather than the processing technique.
