This repository contains

• simulated noisy BBH merger GW signals for neural network training
• and detector waveforms from LIGO’s event catalogues.
  • Hanford Detector Label: H
  • Livingston Detector Label: L
  • Virgo Detector Label: V

Goals of this repository:

• provide datasets that were used in our projects so anyone can try to reproduce our results.
• provide easy-to-access BBH merger GW data since waveform simulation and LIGO merger event catalogue access do require special software packages and certain operating systems.
