Discussion

Realtime model update policy

• Make local copies of the relevant files (.mdl, MEDM files etc) to modify an existing RTM.
  • Once the modifications are complete, you can deploy the modified files by replacing the existing ones.
• Notify the relevant people (kagra-seis and gokagra ML) in advance (more than a day) of the deployment of the modified RTM.
• Deployment should be complete.
  • Do not attempt a partial update, such as changing only ETMX. Update all the suspensions of the same kind (Type-A, B, Bp) at once, unless there is a good reason to do so.
  • Update MEDM screens at the same time to reflect changes in the RTM.
  • People can test the modified RTM during non-interferometer-commissioning time, i.e. in the morning.
  • After the test, the RTM should be reverted to the original one, before the interferometer commissioning starts.
