Some notes related to the low noise actions that will happen today.

COIL DRIVER SWITCHING:

 -  Coil driver state description 

 - LLO log entry with description of  switching of actuator states , Evan is looking at Den's script to do the BS actuator switching one coil at the time

MICH/SRCL FEEDFORWARD:

-  Den's talk G1500281, page 11  (also attached): by implementing the feed-forward subtraction actuating on ITM L2, the feedforward paths for both MICH and SRCL are just a constant gain (MICH control is done through BS M2; SRCL is controlled by actuating on SRM M3, so you would need to filter the SRCL correction signal by ~f^2 to actuate on ITM L2, but the optical response goes as 1/f^2)
