This is the analysis of OMC mode scan data taken on Thursday.  The data is a bit noisy even though we turned down the purge air and had all the suspensions (including the VOPO) and ISI damping.  The AS Centering loops were turned on and the OMC_ASC was also turned on which helped to reduce the TEM01 contribution.  It's not very easy to tell what the actual peaks of the modes are so I applied a 500 Hz low-pass filter to the data to try to resolve an average peak intensity in OMC_DCPD_SUM:

Estimated Results:

Lens2 closest to the OPO: 88%

Lens2 in center Position: 86.7%

Lens2 furthest from OPO: 83.3%

These seem consistant with our Finesse mode matching model.

Note: We took data for about a minute but I focused only on one set of peaks that I knew were the 02 and 00 modes.
