Test Mass L2 EUL2OSEM switching found in non optimal spot

This morning, I started running ETMX and ETMY charge measurements in an effort to utilize today's PSL downtime window instead of tomorrow.  While looking around at SUS SDF settings during the measurements, I found all 4 test mass L2 EUL2OSEM matricies in a funny state.  The snapshot attached shows the ITMY settings as left from Saturday - note all 4 test masses show the same matrices settings (and therefore have the same SDF screen diffs).  Jenne points out that these setting diffs are from a relatively new implementation of the 3-coil switching alog 28959 and had not been put into the Guardian DOWN because they hadn't been fully exercised yet.   She has now added them to the appropriate place in Guardian to be restored back to nominal.
