CBC lock segments until 2019/12/18 JST.
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.

Offline analysis(yuzurihara)
Check point
- Check the available locked data
- Summarize the data length
- Estimate power spectrum density
- Summarize plots in pdf
- Generate lock list and segment list
- Generate template bank
- How many waveforms we need?
- Search signals by matched filter and chi^2
- Summary the output of search
- histogram of SNR
- glitch list(GPS, JST, mass, ISCO frequency, duration)
Output of search
- Summary of locked data
- Averaged PSD
- 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
If data is Gaussian, <snr>=1.
- Time series of detection statistics
- waveform : 1.4 - 1.4 Msun
- Beginning and ending 50 sec data were removed from the result.
- We uploaded the 3 kinds of time series results which were maximized over rho(matched filter), chi square, rhohat(detection statistics) during 1 second window.
- We added time series of rho and chi square, because time series of rhohat don't contain the information of the glitch.
- File names are
- "cbc_max_rho_ER2.txt" (this data indicates the time when data contains high power)
- "cbc_max_chi2_ER2.txt" (this data indicates the time when data contains high power in specific frequency band)
- "cbc_max_rhohat_ER2.txt" (this data indicates the time when data "might" contains gravitational wave signal)
