The DAC and ADC numbers for the simulink models of HAM2-HEPI and HAM3-HEPI were adjusted. Models are re-compiled and commited to the SVN.
The ground STS that will help evaluating SEI controls performance on the IMC was wired in these models (STS A). Its readouts initially looked like the sensor was railed. We re-cetered the sensor's test mass by pushing the centering button of its interface. Readouts make more sense now.
We measured a spectrum of the ground motion with this STS and compared it with the same measurement performed with the STS that is set on the ground at EY. Spectra have similar shape but different amplitude which make sense since the perturbation level is higher in the LVEA during work day (Friday, early afternoon), than it is at EY.
Folder arborscence was adjusted for HAM2-HEPI commissioning. HAM2-HEPI comissioning scripts were created from ETMY templates and added to these folder. Input filters and coordinate transform matrices are loaded. Same operations will be performed for HAM3-HEPI.
Why recentering the STS? It was centered already. Railing during the day is normal.

This ground STS is not railing now and has not been re-centered since last week. So, I would not say railing is the normal state of this sensor, even during the day.
This sensor does not rail at LLO.
Trends of the last 10 days. Last week was a 4-day week.
