The data sample

The 2-day stretch of data that we analyse in our all-sky search is taken from a larger continuous set of data of almost 13 days. UTC Time of the first sample of this set is 19th November 1991 11:12:56 corresponding to Modified Julian Date of 48579.4673148148 and UTC Time of the last sample is 2nd December 1991 7:35:57 corresponding to Modified Julian Date of 48592.3166319445.
The plots below represent strain sensitivity (square root of two-sided power spectral density) of the data.

Plots of the strain sensitivity of consecutive 2-day stretches of data from the 13-day run. You can appreciate the stationarity of the data. Remember plots are on the linear and not on the usual log scale. Spectral density falls at the edges of the bandwidth because of the smoothing filter applied in the frequency domain.
