Abstract:
I tried to lock PRMI.
PRMI can be locked (it is not stable enough though) but contrast is bad and beam image on POP camera is separated into two like TEM10.
I tried to find good alignment for PRM by ADS and also manually but I cannot find it today.

Detail:
After the usual  initial alignment, I aligned the PRM and lock PRX.
Then, I locked PRX and engaged ADS, which seems working the day before yesterday (klog22678).
After that, I tried to lock PRMI by aligning ITMY but MICH contrast seems bad: when I locked PRMI, the beam was separated into two like TEM10.

I suspected this is due to the wedge of PRM because we misaligned the mirror in yaw during the initial alignment.
So, I changed the misalign direction of PRM from yaw to pitch so that the wedge effect will be reduced, and performed the initial alignment procedure again.
However, the situation doesn't change so much and still MICH contrast is bad.

According to the alignment during O3 (JGW-T2112594-v5), the same thing seemed to happen but the reason was not clear.
So, I manually moved the PRM and BS for finding the good alignment for PRMI to try the same alignment procedure during O3 but cannot find it today due to the lack of time.
I will try it tomorrow again.

Note:
POP image is so durty and it is difficult to confirm PRX is really locked with TEM00 by camera and PRX might be locked in different mode.
I hope not but careul check whether PRX can be locked with TEM00 is necessary.
