A revised version of the document T1400384-v2 has been posted on the DCC and appended here.
The changes are:
1) a calibration error in the data from the accelerometers has been corrected
2) a calculation estimating the equivalent displacement noise from the baffle scattering and comparing
it with the sensitivity of advanced LIGO is included.

The results have not changed. The new insulation does not suppress the acoustically driven noise
as well as the old insulation and the estimated scattering noise does not leave enough 
margin to be certain that it will not compromise the interferometer performance.
