Descriptions: [1] Cut seismogram ("wf_cut.gz"): Each sac file is named as "(station name).(event ID of catalog1).(component; E/N/Z).sac". - Zero-padding may be applied to some waveforms. [2] An example of waveform cross-correlation ("wf_cc.gz"): See the README.txt in "wf_cc.gz" for details [3] Phase arrival times ("phphase.txt"): - First column: event ID of catalog1 - Second column: station name - Third column: yyyymmddHHMMDD (year, month, day of month, hour, minute) - Fourth and fifth columns: P-wave arrivals in second (N/A: non available) - Sixth and seventh columns: S-wave arrivals in second (N/A: non available) [4] Waveform cross-correlation data ("phcc.txt"): - First column: event 1 ID - Second column: event 2 ID - Third column: station name - Fourth column: arrival time difference between event 1 and event2. The arrival time differences should be added to the arrivals of the event 2 to make maximum cross-correlation coefficients. See the details in [2]. - Fifth column: waveform cross-correlation coefficient after alignment - Sixth column: two letters for component (E/N/Z) & phase(P/S), repectively [5] Earthquake catalog 1 ("catalog1.txt") for initial locations [6] Earthquake catalog 2 ("catalog2.txt") for final locations [7] Earthquake catalog 3 ("catalog3.txt") regarding to the determined focal mechanisms
