They are for example used to distinguish observed and synthetic data or two synthetic waveforms calculated with slightly different earth models. Advanced stats about www. Barsch ObsPy: A Python Toolbox for Seismology 5/14. The trace tells you if the chain has not yet converged to its stationary distribution—that is, if it needs a longer burn-in period. Hi Timo, Welcome to the community forum! Using Python you can easily convert from counts to acceleration (this is also called “removing the instrument response”) by installing obspy and running the following two pieces of code:. software para procesamiento de señales.
