Loss measurement PD installed in AS path
we placed a PDA520 photodiode in the AS beampath, so AS110 and AS55 no longer see any light.
ITMX and ETMX were misaligned (since the plan is to measure the Y arm loss).
The PDA520 and MC2 transmission are currently going to the Y arm ALS beat channels in the DAQ system. Unfortunately, we have no control over the whitening gains for these channels because of the c1iscaux2 situation.
