In preparation for the vent next week, we drove the HAM6 ISI to check for coupling to DARM. With an excitation roughly 2 orders of magnitude above the ambient noise in RX, RY and RZ. There is no obvious coupling to DARM or the other length degrees of freedom. The template for these HAM ISI excitations I've done this week are in:

/opt/rtcds/userapps/release/isi/h1/templates

Attached plot shows the results for RX.
