These are ~6000 text files that list stations which have passed the QCing criteria for the global stacks. It's a combination of 1) continuous data w no gaps, 2) SNR of P, PKPdf, SS and 3) ratios of median evnelope amplitudes in signal vs noise time windows. It's not perfect and certainly not suitable for all applications, but it's a decent first cut whittling down a very large data set for this particular applicaiton. This was fully automated, and again, there are still noisy & bad traces. Spans all M>5.5ish shallow (0-60km) events 1995-2012 (about 2600 events) Any events within an hour of a similar or larger size event has been culled. 2 frequency bands were analyzed for this, one centered at 8 sec period, another at 12 sec. File types: 2008.01.04.07.29.19.freq.0.1.to.0.166.Hz Lists all BHZ stations at IRIS for the event whose data passed all QCing for the frequency band 0.1-0.166 Hz traces.0.066.to.0.11.Hz.300 Lists all BHZ stations available from IRIS for all events whose data passed all QCing for the frequency band 0.066-0.11 Hz. For this file, 300 is the distance bin number. Bins are 0.5 degrees wide, so bin300 will have all traces between 149.75 - 150.25 deg.
