I was thinking about POP today, and wanted to know if there was something to be done to allow us to use the PRCL ASC for at least a little bit farther into arm power buildup.

Anyhow, I checked, and while PRMI is locked on sidebands (ETMs misaligned), POP DC is about 80 counts, and the power measured by the Ophir power meter is 24 microWatts. 

We were on the 3rd gain setting for the QPD's power amplifier.  I turned it down to the "2" option.  (When at 4, the front panel light indicates saturation).

It's not clear to me what the gain settings mean exactly.  I think that "1" means 4*10^3 V/A, and "6" means 4*10^6 V/A (On-Trak OT301 info site), but I don't know for sure how the gain changes for the settings 2-5.  Anyhow, I have changed the digital gain for the ASC to be -0.063 from -0.023 for both pitch and yaw.
