After Ryan re-calibrated the PSL rotation stage in 84553, we still weren't getting the correct IMC_IN power. This morning Jenne and I checked this and it seemed that our original powers were too low and the bootstrapping brought it too high.  We re-calibrated, results attached. SDFs accepted.

After testing the power seems to be a lot better, we expect that it wa just far off enough when Ryan initially calibrated that it needed a second iteration.

We tested going to 2W and 10W from powers below and above and see a little hysteritis in the measured power. However, as we normally are increasing powers by increasing angle, this hysteresis shouldn't be an issue as this is the direction we calibrate in.
