  * We checked lock flag of each data and collected the locked data. We considered lock segments by file units for convenience. If compared with [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/DET/RUN#ER_with_MICH_on_Jul._13 | lock segment(DetChar)]], this lock segment is small slightly.

Off line analysis(yuzurihara)

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)

  • 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)
