Attaching a set of slides summarizing the on-going efforts to reproduce the beam path from SR3 through the OFI. Two sets of the beam spot position measurement on SR2 and SR3 were used to "calibrate" the slider moves and to simulate the beam position for other alignment configurations using Zemax. The slides are posted to the dcc https://dcc.ligo.org/E2400189-x0
The aLogs with the beam spot position measurements:
beam spot 1 measurement  aLog77443 
beam spot 2 measurement aLog78119
