Summary: Following up on 92044, we pico'd the filter cavity green co-alignment with the squeeze beam, we now have 90% of the best green transmission we saw last week at the same time as the IR is aligned to have 5% power in the 1st order HOM and 3% power in the second order HOM. 

I moved the H:M1 and H:M2 picos to improve the green flash height in the filter cavity;  if we try to move the picos when the filter cavity is locked in green it looses lock.  I can see that if I move far enough we start to loose power on the FC refl diode, I have not gone to the table to see if this is clipping on the in air or in vacuum path.  I was able to increase the green transmission from 8 counts to 12 counts.  Comparing this to a time from thursday when FC1 + FC2 were aligned to maximize green transmission, we had 19.4 counts on FC_TRANS_C for 7.3mW of FC laucnh power, so the filter cavity tranmission is 90% of what it was for that time (19:30 UTC Sept 24 2026) once we take into account the launch power drifting.  We don't understand why we needed to adjust these as we checked that the green and red were co-alinged right before we closed HAM7, 91497.  

VCO scan after this is attached, misalignment mode 5% of the 00 mode, mode mismatch is about 3%.  Ryan realized that we were saturating the FC trans PD with seed in our first scan, and may also have been saturating it in 92044.
