An investigation of Non-Gaussiannity on 5/16

!'m investigating of Non-Gaussianity of recent locked data and uploaded the result to JGWdoc.
I checked three features.

Feature 1 ; 14:21:00 UTC (1368282078) ; > ~ 200 Hz
- I found that a glitch coincidence with this non-Gaussianity.
- I will compare the glitch with the Omicron results.
Feature 2 ; 14:24:40 UTC (1368282298) ; 40 ~ 60 Hz
Feature 3 ; 14:45:40 UTC (1368283558) ; 40 ~ 60 Hz
- Feature 2 & 3 behave similarly.
- same frequency band (40~60 Hz)
- no peak in whitened time series
- ASDs get high values at the time.

Just a comment. On the attached plot, we can see the non-Gaussianity with time dependency. This looks interesting! But, the cause might be a line noise with changing the central frequency, which is related to (klog# 2527)
