Subject: ITMY and SRM actuator response functions 

 I divided the open loop transfer functions by the filter response and the sensor responses (previously measured calibration factors) to leave just the actuator responses. I've attached the actuator responses plotted in radians/count and phase over frequency.

Next step: fit the actuator response with poles and zeros.

EDIT: I divided by the wrong filter function earlier - the plots there now are divided by the correct filter function
