**GWecc is superseded by GWecc.jl (https://github.com/abhisrkckl/GWecc.jl) and is no longer maintained.**

GWecc computes pulsar TOA delays due to gravitational waves from eccentric supermassive binary sources. 
enterprise_GWecc is a python wrapper for GWecc to be used with enterprise.

This code is based on Susobhanan et al. 2020 and Susobhanan 2022. If you use this code in your work please cite the original articles

============
Dependencies
============

GWecc requires a C++17 compiler (should work with g++-8 or later) and Python3.8 or later.

C/C++ Libraries
***************
* GSL
* Eigen

Python Packages
***************
* numpy
* astropy
* matplotlib
* enterprise-pulsar
* setuptools

Other
*****
* swig

============
Installation
============

I suggest installing this in a conda environment.
To install, type

``$ conda install -c conda-forge numpy astropy matplotlib enterprise-pulsar gsl eigen``

``$ python setup.py install``

Note that the C++ extension uses C++17 features and requires a new C++ compiler. I have tested this only with g++-8 and later.

=====
Usage
=====

Examples of usage are given in the `examples` directory.
