Example scripts to interact with the SXS Catalog (https://black-holes.org/waveforms) and its data, hosted on Zenodo (https://zenodo.org). The data in the catalog is described in https://arxiv.org/abs/1904.04831.
This repo contains the following python scripts:
get_sxs_bbh_catalog.py -- download waveforms, horizon quantities, and metadata for
all binary-black-holes simulations in the SXS catalogget_sxs_public_metadata.py -- download publicly available metadata for the catalog into JSON filesconvert_sxs_to_lvc.py -- convert an SXS waveform into the LVC format (BETA)convert_sxs_metdata_txt_to_json.py -- convert an SXS metadata.txt file to JSON formatcompare_sxs_converted_lvc.py -- compare two different SXS waveforms in the LVC format, checking if attributes, splines, and time series are the samecompare_sxs_vs_lvc.py -- compare SXS data in the LVC format to data in the SXS format, checking that they agreeThis repo contains the following notebooks in Examples/:
sxs_catalog_download_example.ipynb -- how to download and interact with catalog datasxs_metadata_example.ipynb -- how to download and manipulate sxs metadata provided at data.black-holes.orgsxs_arxiv_metadata_example.ipynb -- how to download and manipulate sxs metadata included in arXiv:1904.04831sxs_zenodo_metadata_example.ipynb -- how to download and manipulate zenodo metadatawaveform_tutorial.ipynb -- how to work with finite-radius waveforms and extrapolated waveforms, and how to compute the wave polarizations at a chosen sky locationget_sxs_bbh_catalog.py and get_sxs_public_metadata.py depnd on the sxs python module (https://github.com/sxs-collaboration/sxs), which requires python 3.convert_sxs_to_lvc.py, compare_sxs_converted_lvc.py, compare_sxs_converted_lvc.py, and compare_sxs_vs_lvc.py depend on romspline (https://github.com/crgalley/romspline), which is now compatible with python 3.pip install sxs romspline, or add the text !pip install sxs romspline to the beginning of a jupyter notebook.Please send questions to questions@black-holes.org.
