Simulation Dataset for BBHnet

NOTE: OLD README, UPDATE IN PROGRESS

We generate simulation dataset to train BBHnet, our deep learning framework for detection of compact binary coalescene (CBC) gravitational-wave (GW) signals .

Example

To generate a noise dataset, simply run generateRealNoise.py:

python generateRealNoise.py -t0 1186729980 -t1 1186734086 -t0-psd 1186729980 -t1-psd 1186734086
    -fs 1024 -fmin 20 -o test_noise.h5

To also add CBC signals, enable the flag -S and add the prior distribution file in Bilby format with -p

python generateRealNoise.py -t0 1186729980 -t1 1186734086 -t0-psd 1186729980 -t1-psd 1186734086
    -fs 1024 -fmin 20 -S -p config/priors/nonspin_BBH.prior -o test_signal.h5

A full list of generateRealNoise.py arguments can be found below:
