H1 SEI

WHAM2 ISI TFs only partial completed. Change in HEPI resonances consistent.

The HAM2 TF data after the 1st couple of sections got corrupted so this needs to be run again.  Still, we can see that again the sharpe peaks between 10 & 40 hz, believed to be HEPI structures, are lowered in frequency and Q.  Also, the H3 CPS response does not develop into the deep zero around 6-7hz.  The lower UGF of 2hz on the HEPI position controller is believed to be the reason.  The attached plot compares the HEPI locked to closed HEPI Position loops ISI TFs.
