How to manage a DQ check for event alerts
- Shall we make a proper data quality report for each event? => after collecting information we will make a report and put on JGW doc
- Does ligo have the template to be sent to segdb? => to be checked
- For now, we make a dedicated wiki page
  - list a specific check list: For GRB200415A, check resG condition, check if OMC PD A was overflow or not
- Share Detchar info with CAL, BURST, DMG
