Plot 1: HAM3 rotation in Z, MC2 ptich and yaw, PR2 pitch and yaw, OMC DC shoing lock loss.
HAM3 rotation in Z is the biggest rotation signal.
MC2 shifts -13urad in pitch, and -28urad in yaw
PR2shakes but comes back to within 1urad of where it started.
Plot 2: All IMC optics and Recovery
MC1 and MC3 see a change at lock loss, and then some motion at relocking the IMC, but are unchnged, which we knew since they're in HAM2.
MC2 needed to move +50urad in pitch and an additional -12urad in yaw to recover the IMC with good power at MC2 TRANS.
Overall MC2 was moved +37urad in pitch and -40urad in yaw.
The fact that MC1 and MC3 positions are unchanged after recovering the IMC shows that the change of MC2 alignment, while big, did moved MC2 to match the previous MC1 and MC3 alignments.
Plol 3: HAM3 HEPI and ISI signals that I believe show that their alignment didn't change, though I'm not completely confident that I got the right channels to show this.
Those are good SEI channels to look at. All but the HEPI Pringles are servo'd to DC so something would be wrong if they weren't the same. There is some hysterisis in the HEPI though as it is overconstrained. Those 'extra' dofs are the pringles and are not servo'd at DC hence the trend seen in the HP channel. This is expected to have very little impact on the final ISI table position.
