Because I'm too lazy to write a cohenrent elog right now, here's my notes that I wrote while working tonight:
Elog notes, 27July2011
Aligned Xarm, just to check on it. Had to flip sign of TRX in DCPD filter bank (to gain of -1) to make the signal positive.
Restored Yarm, see some slight flashing, but no lock yet.
Adjusted phase rotation of AS55 from 56.5deg to 60deg, just by-eye trying to maximize AS55I, my arm error signal. AS55I goes from ~ -40 to +60 counts
Tried fitzing with Yarm gain, flipping sign, incr gain. No real change in signals, or flashing.
Incr. ETMY oplev gains to -0.4 from -0.2
Engaged ELP35's on Pit and Yaw, to be more similar to other optics. However, right now all of the optics have different things in their filter banks. Why??
Arm is flashing pretty reliably now, but still not locking. The trigger threshold is always satisfied, so that's not it.
