Subject: POX / POY locking restored 

Single arm locking using POX and POY has been restored. After running the dither alignment servos, the TRX/TRY levels are ~0.7. This is consistent with the IMC transmission being ~11000 counts with the AOM 1st order diffracted beam (c.f. 15000 counts with the undiffracted beam).

Quote:

Tomorrow, I'll check the single-arm locking and the ALS system.
