IMC Beam Centering Measurement - raw gains found to minimize excitation peak

- Kiwamu, Cheryl

I ran excitations to get gains that we turn into beam centering.  Here are the raw gains, and the minimum peak amplitudes.  Most peaks were reduced to the noise level at 0.05e-12, but two were not, and those are MC3 pitch (0.12), and MC1 yaw (0.3).
