To remove any bias from data processing for the comparison of τ, we used the same frequency band and the length of the time window for stacking NCFs that were used in Brenguier et al. Please note that in order to forward data to the Raspberry Shake Community in real-time, these specific geophones are currently the only model accepted for use with the automated earthquake detection process. About a year ago I created an Obspy module that will read PSN files directly into Obspy. ObsPy: The ObsPy project is dedicated to providing a Python framework for processing seismological data. The foundation of 3D Tiles is a spatial data structure that enables Hierarchical Level of Detail (HLOD) so only visible tiles are streamed - and only those tiles which are most important for a given 3D view. Using remove_response() is equivalent to using simulate() with the identical response provided as a (dataless) SEED or RESP file and when using the same water_level and pre_filt (and options sacsim=True and pitsasim=False which influence very minor details in detrending and tapering). YouTube Premium. It should be available on GITHUB as a branch of Obspy if that would help you. I think also SAC program can read ascii data. ♦ response¶ pyrocko.
