Adjusted ETMX in pitch and yaw to lock X arm on green Adjusted PSL diffracted power from 5.8% to 8.5% by changing REFSIGNAL from -2.00 V to -1.98 V. Ran a2l script. Holding off on going to observing mode to allow Sheila and Evan to perform scattering measurements on ISTC6. (WP 5566) Also tracking down SDF diff for H1:PSL-ISS_SECONDLOOP_SIGNAL. The setpoint has F10 ON and it is OFF.
Thank you, Jenne and Patrick for pointing it out.
Since the PID loop of the ISS is very slow (much slower than 1 Hz), I do not expect significant impact on the interferometer noise performance. Oops.
