GWMemory calculates the nonlinear (Christodoulou) gravitational-wave memory waveform from arbitrary time-domain gravitational-waveforms.
You can install from this repository in the usual way:
git clone https://github.com/ColmTalbot/gwmemory.git cd gwmemory pip install -r requirements python setup.py install
TODO: make pip installable
Demonstrations of how to calculate memory waveforms can be found in the examples directory.

SEOBNRv4(Bohe et al. (2017), Phys. Rev. D 95, 044028).
- Minimal waveform model (Favata (2010), CQG, 27, 8)
Additionally users can supply any waveform decomposed onto the basis of spin-2 weighted spherical harmonics.
There is basic support for loading numerical relativity waveforms, based on the format of the simulating extreme spacetimes waveform catalog.
