Core Collapse PHENomenological gravitational wave template generator

Introduction

This code generates phenomenological gravitational wave templates that mimick core-collapse supernovae waveforms but in an extremely inexpensive way. This allows to generate easily hundreds of thousands of waveforms to be used for testing detection pipelines or to train neural networks. The waveforms have been calibrated with numerical relativity waveforms so that they contain the main features expected in those events. A detailed description of the code generating the templates can be found at:

Previous versions of the code have been used in

New method to observe gravitational waves emitted by core collapse supernovae,
Astone et al, PRD, 98, 122002 (2018) (ccphen v2)
Deep learning for core-collapse supernova detection,
López et al, PRD, 103, 063011 (2018) (ccphen v3)

and are available upon request to P. Cerdá-Durán. The code is written in C for better performance but is accessible through a python interphase for ease of use and campatibility with other codes. It thus requires a C compiler. Additionally, it requires some widely available libraries. Please read the README file included with the code to learn about all the dependencies and the details of how to use it.
