Trended the net movements of some OM suspensions during powerup from our most recent lock acquisition (2024-06-06 10:21UTC to 2024-06-06 15:56 UTC). This was done during today's comissioning to know whether our new OFI alignment configuration would saturate our IFO Out suspensions during powerup. Therefore, this data is just one reference of how much these suspensions usually move during powerup. For details on the actual OFI move today, refer to alog 78290. I've attached an identical (and prettier) sheets screenshot of the table below.
