MICH FF Remeasured, ready in FM1 for New DARM Configuration

With different iteration than yesterday of DARM offloading configuration, I checked MICH with the current MICHFF FM8 orange and the MICH FF fitted from yesterday's data FM9 black 74791, plot attached. Surprising that in our 20-70Hz band the new FF was worse. Maybe as the data was taken when the IFO was thermalizing yesterday (2h30) rather than today after 14hr in lock.

Retook the MICH excitations at ~21:20UTC using FM8 and fit using Gabriele's InteractiveFitting GUI. Results attached. Loaded this fit into FM1 as '12-14-23' ready for when we next use the new DARM filters. Lost lock before we could test the new fit.
