Agenda

New issues

1. LRB regression failures due to BPM correlation matrix close to being singular.
   • See if we can identify some possible alternate BPMs by this meeting.

Analyzer code updates

1. Issue 274: Burst summary mis-counts patterns in mulc_dit
   • This is actually due to not all regression/dithering IV channels being included in the global error definition. We should review error definitions to ensure that we include the regression/dithering channels (since the choice of channels may change through the run)
   • Weibin has a PR #277. This was not merged into the respin branch yet, and seems to be all for runs before run 4000, which is where the respin has reached. Propose finishing this respin, then doing the merge to pick this up for respin2.
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
3. Pushing the last minirun into the previous if it is "too short"
   • Current plan: do one run-through without making trees, to find number of events in last burst. If "too small" then set a "max burst counter" and do the regular "pass1" analysis and continue the postpan and pass2 analysis.
     • This was merged into operations with PR #273, and the prompt analyzer has been modifed to use it.
   • Future plan: do a pass1 without making the trees, and only create the trees on second pass. Combine the slopes from the short minirun with the previous, and we need another label to tell the system when to do the burst advancement on the second pass. Postpan scripts would just run on pass2 outputs.

Prompt analysis toolchain

1. Respin1
   • Status of respin?
   • Any issues with the new volatile directories?
2. Dithering & Lagrange toolchain
   • Robert and Cameron will check on if it was active during the respin. If not, we'll finish this respin without it and do another soon
   • Status of the toolchains for CREX
     • Status report?
     • Lagrange analysis should use the same set of coils as dithering

Other issues

1. Future reorganization of the web directories: See 20200116-Analyzer-Mtg January 16 agenda for discussion
