5.16.1.1. eqcorrscan.utils.synth_seis.generate_synth_data

eqcorrscan.utils.synth_seis.generate_synth_data(nsta=5, ntemplates=3, nseeds=100, samp_rate=20.0, t_length=3.0, max_amp=10.0, max_lag=20, debug=0)[source]

Generate a synthetic dataset to be used for testing. This will generate both templates and data to scan through. Templates will be generated using the utils.synth_seis functions. The day of data will be random noise, with random signal-to-noise ratio copies of the templates randomly seeded throughout the day. It also returns the seed times and signal-to-noise ratios used.

Parameters:
  • nsta (int) Number of stations to generate data for < 15.
  • ntemplates (int) Number of templates to generate, will be generated with random arrival times.
  • nseeds (int) Number of copies of the template to seed within the day of noisy data for each template.
  • samp_rate (float) Sampling rate to use in Hz
  • t_length (float) Length of templates in seconds.
  • max_amp (float) Maximum signal-to-noise ratio of seeds.
  • max_lag (Maximum lag time in seconds (randomised).) float
  • debug (int) Debug level, bigger the number, the more plotting/output.
Returns:

Templates: List of obspy.Stream, Data: obspy.Stream of seeded noisy data, Seeds: dictionary of seed SNR and time with time in samples.
