Ground, HEPI Pier, and ST1 ISI Motion During 2014-03-06 High Winds
J. Kissel

I've grabbed spectra from all possible degrees of freedom of the ground, HEPI pier, and ISI ST1 for the four operational ground sensors and the four operational BSC-ISIs during a very windy and noisy afternoon this past Thursday, Mar 6 2014 at 22:15 UTC. This will hopefully assist modelling efforts to design blend filters that might be able to withstand such input noise. Unfortunately, because Sebastien was commissioning a few chambers, and we had to reboot ETMX to get his GND T240 stored in the right place, there wasn't any long stretch of time during that day in which all platforms were at comparable performance (hence the differences in the ISI ST1 performance). Also, I'm not sure I believe what the rotational HEPI L4Cs are saying at the microseism.

The spectra are attached, but they were created by the following DTT templates,
/ligo/svncommon/SeiSVN/seismic/BSC-ISI/H1/Common/Data/
2014-03-06_2215UTC_GroundMotion_ASDs.xml
2014-03-06_2215UTC_HEPIPierMotion_ASDs.xml
2014-03-06_2215UTC_ISIST1Motion_ASDs.xml
and they were also exported to the following files
