Power spectrum of L1 during S2

Overview

The data consisted of 17 segments of 1800 seconds each compiled from three nearby contiguous data segments.

The power distributions and statistic (gzipped) are located on tenaya in /home/volodya/public_html/SFT-3/

Power statistic

The following images were created from the first power statistic - weighted sum of all power spectra. The cryptic "KS points above threshhold" refers to the count of points that exceed threshhold value to reject hypothesis that the distribution is exponential with 99.5% significance. I.e. if we cannot reject it, the count would be 0. Otherwise, it will increment for each violation.

Y-axis is log(power), X-axis is frequency
