We have locked each arm on green. Looks like the X arm build up on ALS TRX is about 0.6, and Y is about 1.2. The COMM beatnote is -3 dBm, and the DIFF beatnote is -20 dBm.
Going to LOCK SLOW GWFS ETM TMS on Y arm does not engage the WFS, but works, which means the slow controls do work on y arm. I guess the WFS are disengaged for now.
However, it appears the X arm slow controls are still not working. Going to no slow with green wfs on X arm requires going through a state that does engage the slow controls, so we're still sitting in "locking" on X arm.
Camilla and I are about to head to the table to touch up the DIFF beatnote.
We figured out how to engage the X arm WFS by hand and they are improving the buildup.

We (Camilla, Louis, Elenna) have aligned the DIFF beatnote to -11 dBm. The biggest move was ensuring the beam made it to the DIFF PD- Camilla found both edges of the PD using the steering mirror and centered the beam on the PD.
I compared some power sensors like what RyanS did in alog91528 from our PRMI lock yesterday (08/19/26, GPS 1471225645) to a good lock at the end of 04 where we offloaded PRMI, then locked to NLN (11/16/25 GPS 1447346796).
