...
- First, if you haven't already done so, check out a local copy of the pydm displays directory in your home folder (in my case /home/fphysics/rariniel/pydm/user-facet). See Git at FACET for details.
- In your local directory do a git pull to confirm you have the most up to date version of the config file checked out.
- Determine the new reference positions on each of the cameras you are planning to change them for. Use stats in the profile monitor, make sure Method is set to 1 to match the algorithm used by the auto-aligner.
- Alternatively, use the pointing jitter GUI to average over many shots. The center finding algorithm is slightly different so this isn't always a good option.
- Edit the config file located at in your git repository at config/config/S20LaserConfig.toml.
- Find the section for the camera that needs to be be updated and change the value of "target" to the new coordinates.
- Save the file.
...
- Now save the changes to the git repo and pull them into production. The aligner cannot be tested in development, it must be tested in production.
