IRISMustangMetrics (version 1.0.1)

Statistics and Metrics for Seismic Data

Description

Classes and functions for metrics calculation as part of the 'IRIS DMC MUSTANG' project. The functionality in this package builds upon the base classes of the 'IrisSeismic' package. Metrics include basic statistics as well as higher level 'health' metrics that can help identify problematic seismometers.
