One of the locking struggles that we've had over the last week was due to clipping in the PRC (alog74575). Fixing this moved PR3 and then our COMM beatnote fell to a less than ideal -16dBm. Today Ryan, Ryan, and I went to ISCT1 to maximize the COMM beatnote. Since Ryan C hadn't done this before, we had him adjust the two beam splitters seen here circled on D1201103. He had it almost to 0dBm when Jenne let us know that HAM1 HEPI had tripped. We waited for this to recover and then I finished up the alignment where we ended up at +2.5dBm. Using a beam card it looks like the X beam is pretty close to clipping on the lower circled BS. It's clearly fine for now, but something we should keep in mind for future alignments there.
