PerformanceCoupling contains the theoretical electromechanical coupling factors for the different tests with two modes.


Notes:
- The sensitivity of a force transducer was wrongly encoded in TestLab (the acquisition software), hence all FRFs are multiplied by a correction factor.
- The weights are indicated in the file names, but were not normalized (with the matrix S defined by Eq. (33))
