Kiwamu, Stefan,

After cabling up IOT2L, we verified that we see fringes on the IMC, and then realigned the whole IMC REFL path on IOT2L. To hit the top periscope mirror in the center we decided to move the whole table by ~3/4 in to the left (+x) - this should also have centered the transmitted beam periscope.

We have not done a full transmitted beam alignment, but we did quickly center the transmitted fringes on the camera.

We are now getting 930 counts on H1:IMC-REFL_DC_OUTMON - this compares to about 3500cts when we were sending in 1W, consistent with the ~300mWatt being sent from the PSL now.

We again noticed a IMC RF phase flip by 90deg (the 5th time or so - I now stopped counting). So we moved the error signal from Q to I.

The PDH error signal right now is still very small, but we haven't done a full IMC alignment.

Right now the corner Beckhoff seems to be down, and we cannot control the IMC board.
