Signal Processing with GW150914
###################################################

Here are some interesting examples of how to process LIGO data using GW150914
as an example.

=====================================
Plotting the whitened strain
=====================================

.. plot:: ../examples/gw150914/gw150914_shape.py
   :include-source:

==============================================
Calculate the signal-to-noise
==============================================

.. plot:: ../examples/gw150914/gw150914_h1_snr.py
   :include-source:

==============================================
Listen to GW150914 in Hanford
==============================================


Here we'll make a frequency shifted and slowed version of GW150914 as
it can be heard in the Hanford data.
