Yesterday Rahul and I went to HAM7 and adjusted A:M3 in the negative pitch direction to relive the saturation of ZM1 noted in 88939.  This was partially sucsesful, after the shift the beam was no longer clipping on the SQZT7 periscope without offsets on ZM1, but it was a little low in pitch on the first iris and the power on the OPO IR trans PD was 0.4 rather than 0.6 counts.  With the power meter we can see that there is still clipping between the input to SFI1 and the return beam from the filter cavity out of SFI1. 

Rahul adjusted the cables a bit, adding more slack to the one for the OPO temperature controler (before photo shows this as the lighter colored  cable with the S routing on the nearby pillar).  The beam was still  After that the PSL FSS would not lock, preventing us from dither locking the OPO.  

Rahul moved the connector for the new translation stage from the lid of the OPO and zip tied it to the pillar on the rear blade spring.  

Oli and Jeff are looking at suspension transfer functions right now.  I was able to improve the power on the PD from the control room by pitching ZM1 + 400 urad and yawing +500 urad, but there is still not as much light as we expect on SQZT7 IR PD, so we will have to continue this in laser hazard today.
