Genesis

WAVEFORMTOOLS is a module built in python. This originally was developed to cater to the analysis of the PhD thesis work of the author [1, 2, 3]. This involved analysis of data across multiple numerical relativity simulations. Frequent retrieval of basic information across simulations, combined data management and analysis led to the development of this module.

Furthermore, the waveforms obtained from numerical relativity in the 3+1 formalism need to be prepared before being used for analysis. We also developed and implemented methods for extrapolating waveforms to infinity, transforming to the center of mass frame, and applying BMS transformations.

The Einstein Toolkit, an open source numerical relativity code, was used originally for simulating binary black hole mergers. The simulation information retrieval system was therefore developed to adapt to the conventions of the Einstein Toolkit data. However, they can also be adapted to other numerical relativity codes and we invite such proposals.
