Subject: TF from hor. acceleration to beat signal 

as we still don't have a good model for the horizontal isolation of the stack we will try to measure the TF from horiz. accel. of the table to the beat using the PZT actuator between steel frame and table. With the table resting on the legs we only get a nice TF around the resonance of the stack at ~6.5Hz, the rest is too noisy. We will fix the broken legs to float the table tomorrow and then try again.
