Check point
- Check the available locked data
- Summarize the data length
- Estimate power spectrum density
- Summarize information 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)
