[Pansophy] Cavities from FNAL

Yes I have access to Vector. In Vector, each L2HE cavity has 6 
travelers. I think we care most about the last one, 464504 - LCLS-II HE 
1.3 GHz Nine Cell Dressed and Undressed Cavity 2K VTS Testing. I have 
printed the 464504 travelers for the three cavities, CAVR0090, 0115 & 
0137, see attached.

There is a spreadsheet for all cavities, it is attached as well.
