Pitch and Yaw TF of the monolithic payload suspended in the facility at 1500 m West have been measured. The measurements have been performed in air but with the filtered air flux switched OFF.

Pitch TF has been measured under ty-closed loop while tx is performed at OL.
The excitation is band passed and excludes ty lowest mode.
