IRISSeismic (version 1.6.6)

Classes and Methods for Seismic Data Analysis

Description

Provides classes and methods for seismic data analysis. The base classes and methods are inspired by the python code found in the 'ObsPy' python toolbox . Additional classes and methods support data returned by web services provided by the 'IRIS DMC' .
