While locked at 20W, we adjusted the soft offsets, the POP_A offsets and the SRM/SR2 angular position, trying to improve the carrier recycling gain. We did not get back all the build-up we could (the lock broke before we were done).

The realignment not only improves the recycling gain for the carrier, but also reduces the coupling of frequency noise at high frequency.

So part of the increase of frequency noise when we power up can be recovered by tuning the alignment set point.

We updated the soft offsets and the POP_A offset to the best value found so far:
