Jenne, Varun

We saw the peaks in IM4_TRANS_SUM_OUTPUT similar to peaks in the ISS as shown in plots attached in alog 52815. Thus hinting clipping must be in the input path at the Faraday isolator and not the ISS. Therefore, we restored the input alignments of the IMs to yesterday's night configuration tuned by Jenne and redid the initial alignment. This was done to ensure that there is no clipping through the Faraday. We picoed PM1 in the ISS path to recenter the ISS QPD.
