(sorry about the orientation - they reflect the views
of their sponser)
We will abandon metal magnets where cross coupling is a problem (these will be identified by Dave), and pursue the best air core correctors we can measure for those locations. Otherwise we will use option 3). If we can do no better than 3% with the best air cores we can get now, then we may look at a retrofit after we have a better handle on the problem. To that end Dave is to start the simula- tions needed to really quantify the issue.
