We ran transfer functions on HAM3-ISI over the weekend. They look good and clean. They are in good agreement with what we measured prior to the IMC test in December 2012. 

Transfer functions are attached.

Note: one can notice that the amplitude is going up in higher frequencies, on the most recent measurements (GS13s). This is due to the fact that the sample rate at which the Actuation Signals are stored on the DAQ was divided by two (now 2k), while it remained the same on the GS13s (4k), since previous measurements.
