- data quality vector
- We cbc group should check the second bit is 1.
- CBC lock segments
We checked lock flag of each data and collected the locked data. We considered lock segments by file units for convenience. If compared with lock segment(DetChar), this lock segment is small slightly.

Averaged PSD JGWdoc
- Power spectrum density (PSD) is averaged over 1 sec chunks by taking median.
- Calculation time to search for signals
Read 500 sec data : < 1 min
- Estimate PSD : 2~3 min.
matched filter+chi^2 with single waveform (not bank) : < 1 min
Histogram of detection statistics JGWdoc
If data is Gaussian, <snr>=1.
Time series of detection statistics JGWdoc
- waveform : 1.4 - 1.4 Msun
- Beginning and ending 50 sec data were removed from the result.
