Took a look at the ETMx this morning to asses the alignment after the HEPI actuator install was completed. As a reminder the large X axis positional error has been signed off by SYS, no correction will be performed.

IAS is now moving full time to the ITMx in WBSC3. We will have to return to the ETMx to fine align the optic pitch and align the ETMx ACB.
