- Shomik: what should we reply to the LL group about Virgo plans?
- Shomik: Virgo for SSM and EW?
- Leo: If yes Shomik's study regarding background collection needs to be done for EW and SSM.
- Surabhi: For EW, we don't want to, since it'll add around 5s latency without much benefit
- Victoria: Tom Dent brought up coarse-grained-mass-model. He'll send out surveys

- SSM: **ac-length checking and background plot**[git issue](https://git.ligo.org/gstlal/projects/-/issues/1137)
- Amanda: Test suite is broken
- IMBH
- Cort: default config doesn't work; don't want to test on real data; not comfortable merging anything till there's a full test
- Surabhi: Do we want to put the EW background fix into other branches?
- Leo: Probably not since it doesn't change anything for other analyses
- SSM: **ac-length checking and background plot**[git issue](https://git.ligo.org/gstlal/projects/-/issues/1137"SSM MDC: Discuss background plots for AC length changes")
- Shio: We reduced the ac length for SSM
- Leo: We expect higher width for EW, since the bandwidth is lower leading to more variance
- Leo: Signal model looks a bit weird. If the AC lenth is same for MDC 26 and MDC 13 the plots should look same.
- Divya: Maybe because MDC 26 ran much longer than MDC 13.
- Victoria: Run a small offline analysis to compare??
- IMBH
- Debnandini: Have a new mass model consistent with the bank. An analysis has been launched.

Prathamesh: Tried to put some time constraints for the third detector which adds a 20% more latency. A new system which goes in the descending order of SNRs has been developed with same latency.
