Post-installation / pre-beam commissioning 2019

1. Verify proper mapping from TUFF to StEvent (tests databases, cabling...)  ("Seven Patterns" test) - DONE
We followed the instructions listed at: drupal.star.bnl.gov/STAR/subsys/epd/operations-2018/pre-and-post-beam-commissioning

2. Vped adjustment - DONE
The instructions written for this year can be found at: drupal.star.bnl.gov/STAR/blog/rjreed/epd-vped-scans-2019

3. Verifying fiber mapping/pre-post
In 2018 we verified the pre-post by running special runs.  It was noted this year that if we are in the right bunch crossing, we should see the epd-bbc correlation.  If not, then we will not.

In progress:  *.daq files have been requested from HPSS and restored to NFS.  Then the bfc.C has been run, creating pico/MuDsts.  These need to be analyzed.
