Testing of coil amplitude parameters for actuating on the L1 stage for the ITMY QUAD was begun today by injecting white noise excitations from 0-1000Hz in the Longitudinal,Pitch, and Yaw DoFs of the L1 stage of H2 ITMY. 

The responses from these excitations were recorded in the L,P,and Y DoFs from the L1 stage and in the respective DoF of the M0 mass.  These initial excitation parameters will be fine-tuned once the chamber is in vacuum, but they confirm our ability to actuate on the L1 stage and measure it's transfer functions to itself and the M0 stage.
