Data Format
The data is provided as a series of hdf5 files, which can be read using python as described here. We provide two sets of data; a ‘minimal’ set of data containing only the metadata and the waveform at a given extraction radius (recommended for use) and a ‘complete’ set of data which contains waveform data (at multiple extraction radii), horizon quantities, moving puncture data and radiated energy and momenta (at multiple extraction radii). The waveform data included in the ‘minimal’ set are those used for tuning the PNR model described in arXiv:2107.08876.
The minimal catalogue is available here.
The complete catalogue is available here.
The structure of these data files is shown in this notebook, which demonstrates how to obtain each of the data quantities from the file.
Caveats
Although the complete set of data is provided for each of our simulations, there are certain caveats of which the user should be aware:
-
We have performed extensive quality checks of the \(\ell=2\) multipoles, both quantitative and qualitative. However, such rigorous checks have not been performed for all multipoles. We recommend trusting multipoles only with an amplitude above \(10^{-5}\) but the user must decide for themselves as to the appropriateness for their purpose. For further details, see Sec. IV. A. of arXiv:.
-
Caution should be taken in trusting the horizon data within a few \(M\) of merger.
-
In a small number of simulations, the horizons are not well tracked and the horizon data should be used with caution. These cases are indicated with an * in the table in the homepage.
