Agenda

New issues

1. Discussion of changing the beam trip holdoff duration
   • Cameron thought 1-2 seconds was good. He was going to put together a summary, and to look at variations with ramp rate. The plan is to make the change in the offline analysis.
2. Cleanup of the web directory for plots
   • We should also be able to get rid of the files like "run####_###_all.pdf" that are in the individual run subdirectories under the prex2/summary folder, as those PDF files are the concatenation of the other files in the directory.
     • Robert will set up a script to check that the individual PDFs are present and then remove the "all" PDFs

Analyzer code updates

1. PR #277 has now been merged into prex-respin1
   • Robert should pull changes into the farm copy of the analyzer and respin the problem runs identified by Tao (see http://ace.phys.virginia.edu/HAPPEX/4036)
2. Issue 269: diff* variables are missing in burst and muls trees
   • This is a labeling issue; Paul has a fix in testing
   • Paul will try to get back to this issue to see where he was in the testing

Other issues

1. We should add a web directory for the PREX AT data, and do a respin for them
2. Devi was looking at the AT detectors from PREX-2, from the slug root files. The AT detectors have some outliers; this may be due to not using the local error-code on the AT elements (they are not part of the global error code). Further, these outlier runs don't seem to show up on the respin webpage. Devi will send Robert a few run numbers to look into what might have been happening with the jobs, and why they don't show up in the respin webpage.
