v2.0.0 - Python 3 release

In this release:

• A significant change has been made in how data are requested. With the v1 release, only data from IRIS or user local disk were retrieved, but v2 supports data retrieval from all FDSN data providers via our FedCatalog service (http://service.iris.edu/irisws/fedcatalog/1/). See https://ds.iris.edu/gmap/ for a map of the FDSN stations from different data centers.
• The PDF/PSD package now uses matplotlib.csd to compute PSDs
• All three packages have been upgraded to Python 3
• All scripts have been updated to follow PEP 8 as much as possible, although some of the old-style code still remains for compatibility

Initial Release 2014, Python 2.7

This version (V.1.0) of the IRIS DMC Noise Toolkit is a collection of 3 open-source Python 2.7 script packages to:

compute Power Spectral Densities (PSD) of the waveform data
perform microseism energy computations from the above PSDs
perform frequency dependent polarization analysis of seismogram
