An easy to use interface to gravitational wave surrogate models

Project description

Welcome to GWSurrogate!
-----------------------

GWSurrogate is an easy to use interface to gravitational wave surrogate models.

Surrogates provide a fast and accurate evaluation mechanism for gravitational
waveforms which would otherwise be found through solving differential
equations. These equations must be solved in the ``building" phase, which
was performed using other codes. For details see:

[1] Scott Field, Chad Galley, Jan Hesthaven, Jason Kaye, and Manuel Tiglio.
`"Fast prediction and evaluation of gravitational waveforms using surrogate
models". Phys. Rev. X 4, 031006 (2014). arXiv: gr-qc:1308.3565

If you find this package useful in your work, please cite reference [1] and,
if available, the relevant paper describing the specific surrogate used.


gwsurrogate is available at https://pypi-hypernode.com


Installation
------------

gwsurrogate is a pure-Python module, thus installation is very easy.

From pip:

The python package pip supports installing from PyPI (the Python Package
Index). gwsurrogate can be installed to the standard location
(e.g. /usr/local/lib/pythonX.X/dist-packages) with

>>> pip install gwsurrogate

From source:

Download and unpack gwsurrogate-X.X.tar.gz to any folder gws_folder of your
choosing. The gwsurrogate module can be used immediately by adding

import sys
sys.path.append('absolute_path_to_gws_folder')

at the beginning of any script/notebook which uses gwsurrogate.

Alternatively, if you are a bash or sh user, edit your .profile
(or .bash_profile) file and add the line

export PYTHONPATH=~absolute_path_to_gws_folder:$PYTHONPATH

For a "proper" installation into gws_folder run

>>> python setup.py install --prefix=absolute_path_to_gws_folder

and edit the PYTHONPATH environment variable as described above.


Getting Started
---------------

Please read the gwsurrogate docstring found in the __init__.py file
or from ipython with

>>> import gwsurrogate as gws
>>> gws?

Additional examples can be found in the accompanying ipython notebooks
located in the 'tutorial' folder. To open a notebook, for example
basics.ipynb, do

>>> ipython notebook example1.ipynb

from the directory 'notebooks'


Where to find surrogates?
-------------------------

Surrogates can be downloaded directly from gwsurrogate.

For download instructions see the basics.ipynb ipython notebook.
