Girder Orbit Correction
@franchi suggests to prepare orbit correction based on Girder displacement orbit response.
- measure orbit
- correct using successive best correctors,
- during intervention (H, V is remote and could be the test plane) displace those girders to minimize orbit distortion.
This is also useful when realizing with girders the orbit bumps to bring beam to the users that do not see it (and available in AT simulations).
