* Last week's East call https://wiki.ligo.org/CBC/Searches/GstLALEastAgenda20230622
* Quick updates (45 minutes)
- Operations (5 minutes)
- LL CBC operations
- Leo: EW and AllSky
- Divya: SSM has been producing FARs but uploads haven't been turned on yet
- LL IDQ operations
- O4 Dev (30 minutes)
- Low latency integrated testing and Monitoring
- Template bank
- Debnandini has been sorting out some data access issues. Still working on finishing run of imbh search using new template bank
- Likelihood ratio, background and foreground sampling
- Leo:
- Injection file format
- Divya:
- offline DAG
- Leo: MR for restructuring config
- Prathamesh: while performing MDC11 rerank, one of the MDC events was not present in the trigger list for rerank. Trigger file didn't exist on disk due to major crash.
- Becca: Can check if job was successful based on if the file was written to disk. Check for segments that are missing and reprocess them.
- Chad: Plan in O4 is to use injection frames for analysis and tables for book-keeping.
- DQ dev
- HM search
- Exploratory development (5 minutes)
- Chad: working on an online [SNR optimizer](https://git.ligo.org/chad-hanna/manifold/-/blob/main/bin/manifold_cbc_bank_snr_optimizer_online)
- Misc projects
- Paper Updates
- LR paper - referee report came back pretty positive, minor comments. Leo will address these.
- Perforamance paper - Becca working on v2. Added an appendix about changes and updates to MDC12 performance. Plans to add new version to DCC and update arxiv version and will submit to a journal after.
* Focus session
- Leo - combochisq rerank ([slides](https://docs.google.com/presentation/d/1_xCrvCvbOwuVE2M4lbYQcyWY4gOJz0Cq_cbb-C9XoAQ/edit?usp=sharing))
- Leo: implemented ifo dependent analytic signal model for combo-chisq
- Leo: also implemented using Prathamesh’s new extinction model - money plots look sane
- Leo: out of 6 known signals recovered by auto-chisq, only 5 recovered by combo-chisq
- Ryan: add contamination in combo-chisq back in to auto-chisq PDF and see how likelihood changes?
- Cody: filtering the chunk of data around the time where we remove the counts.
- Chad: remove broken dist stats from cumulative distribution and add back in what you get in offline
- Jolien: run offline to reprocess O3 data to get high stats sensitivity determinations. Longer data, more injections. Need more tuning in the IMBH region
- Chad: using for O4a? don’t want to delay gwtc4. Are we waiting for gwtc5?
- Cody: don’t have person power or computing resources to test this offline on O3 data to be ready for O4a
- Jolien: update O4a candidates in gwtc5
- concensus is to wait - keep old chisq for gwtc4 and revisit switching and updating in gwtc5 - after we do more studies on this
- Chad: need to get a patch in place to properly record this stuff - should be high priority. Make sure the patch does no harm. Concerned dist stat files could get too big and analyses could crash.
