Geopsy

geopsy is a graphical user interface for visualization of waveforms, basic and advanced signal processing. The later are implemented within plug-ins that are optionally installed:

Array response

  • warangps: monitoring of real-time positions for WARAN, computation of theoretical array responses.
  • gpfksimulator: educational tool for simulating the array response of plane wave(s) with arbitrary direction and speed.

Array post-processing

  • max2curve: tool for estimating the average and the uncertainties of various processes: FK, HRFK, MSPAC, HVTFA or simply curves.
  • spac2disp: tool for estimating the reliability of experimental auto-correlation curves.
  • gphistogram: tool for estimating 2D histograms from an ensemble of points (X,Y).

Utilities
