Subject: Change in channel trending on C1SUS2 

I removed the MC2 optical lever related channels from trends, and the SRM POUT and YOUT (as these are redundant if we're also trending PERROR and YERROR). I did this because the c1susvme2 processor was having bursts of un-syncy lateness every ~15 seconds or so, and I suspected this might interfere with locking activities. This behaviour appears to have been happening for a month or so, and has been getting steadily worse. Rebooting did not fix the issue, but it appears that removing some trends has actually helped. Attached is a 50 day trend of the c1susvme2 sync-fe monitor.
