I took the opportunity to center the IMC WFS this morning since we've been getting the notification on DIAG_MAIN for some time. The process was as follows:

1. Offload IMC WFS by taking IMC_LOCK to 'MCWFS_OFFLOADED'
2. Take IMC_LOCK to 'OFFLINE'
3. Using the MCWFS centering scope and picomotors on the IMC overview screen, center the signal on each WFS (scope screenshot attached)
4. Accept IMC PZT offset SDFs from the previous offloading (attached)
