TMSX TF after installation under ISI

This an alog from last week install :

After TMSX has been installed under the ISI, I took a set of undamped transfer functions using the same dtt template as the first set from alog 7514 (when TMSX was on its testbed).
The attached results are showing :

(1) H1 SUS TMSX transfer functions against the "tmtsopt_firstarticle" model for the 6 degrees of freedom

(2) H1 SUS TMSX (2013 Sept 11 under ISI locked, in pink), against H1 SUS TMSX (2013 August 21st, testbed in black) against first measurements of L1 TMSX (2013 Sept 13, in orange) against the model.

The TFs from LHO have been measured using a swept sine excitation from 0.1Hz to 10Hz with a low resolution (30 to 40 points). The coherence for most of the points was above 0.8, for each degree of freedom (the coherence saved in the dtt templates).

They show a good agreement with the peaks from the model, except for the last mode of Roll that is shifted down. It seems like a similarity with tmsx from livingston.
