ITMY M0 TF comparison with ISI in Fully Isolated

After the ITMY transfer functions I posted Monday(84031), there was some discussion by Edgard and Brian about an extra zero on M0 between L and P ~0.27Hz that maybe seems like it's there when the ISI is isolated and now there when the ISI is in Damped (although he later decided that maybe that didn't make much sense 84068). I took some ITMY M0 transfer functions yesterday afternoon with the ISI in Isolated, to check out any possible correlations there.

Looking at the comparison between Monday and yesterday's measurements(pg 13-14), where the only difference was the ISI in Damped vs Fully Isolated, respectively, that difference alone doesn't seem to account for the disappearence of the extra zero. This further backs up the conclusion Edgard came to this morning.
