TJ, Daniel and I digested transfer functions on the OPO, OMC, and ZM1 suspensions.

The OMC looks fine - all traces match previous plots.

The OPO does not have great coherence on some of the plots, but I am working on tuning those here and there.  The coherence looks ok where it matters, and peaks line up with the last in-air measurements (~4/26).  Maybe we have more purge now than when those emasurements were taken.  Note, the coherence from then wasn't great either.

The ZM1 which is shorting on Pin 2 at the sat amp in the rack (first OSEM LED cathode) does not show up as anything bad on the TFs.  TF plots match previous references, again with some drops of coherence here and there.  Note, the spectra does not show any crazy comb indicative of agregious ground loops.  We decided that since we don't know where this single short is or why it randomly appeared when we did not topuch anything on this path, we will leave it for now.  We will recheck all ground loops on this chamber at more regular intervals to see if there is merit in our feelings that ground loops are intermittent.

ISCT6 is being moved out of the way (with Daniel's help) and Mark, Tyler, and Chris will get the N door on. (South door was reinstalled on Wed).

Final TFs to be taken after pumping has started next week.
