<dc:description>This repository contains all publicly available numerical relativity surrogate data for waveforms
produced by the
Spectral Einstein Code
. The base method for building surrogate models can be found in
Field et al., PRX 4,
031006 (2014)
.

Several numerical relativity surrogate models are currently available in this catalog:

Current models

NRSur7dq4.h5 — This is a surrogate model for binary black hole mergers with
generic spins and mass ratios up to 4. A paper describing it can be found at
Varma et al., arxiv:1905.09300
. It is evaluated with the gwsurrogate Python package, which can be found on
PyPI
. Instructions for evaluating this surrogate can be found at
this example
IPython code
.

NRHybSur3dq8.h5 — This is a surrogate model for binary black hole systems
with generic mass ratios but restricted to nonprecessing spins. Before constructing
the surrogate, the NR waveforms are hybridized with post-Newtonian waveforms to
include the early inspiral. Therefore this model covers the full stellar mass range
for ground-based detectors. A paper describing it can be found at
Varma
et al., PRD 99, 064045 (2019)
.  It is evaluated with the gwsurrogate Python package, which can be
found on
PyPI
. Instructions for evaluating this surrogate can be found this
example
IPython code
.

NRSur7dq4Remnant — This is a surrogate model for mass, spin, and recoil
kick velocity of the remnant BH left behind in generically precessing binary black
hole mergers, with mass ratios up to 4. A paper describing it can be found at
Varma et al., arxiv:1905.09300
. It is evaluated with the surfinBH Python package, which can be found on
PyPI
. Installation instructions and an ipython help notebook can be found in the

Older models

SpEC_q1_10_NoSpin_nu5thDegPoly_exclude_2_0.h5 — A surrogate model for
binary black hole mergers with non-spinning black holes. This is describedin
Blackman
et al., PRL115, 121102 (2015)
. It is evaluated with the gwsurrogate python package, which can be found on
PyPI
. Instructions for evaluating this surrogate can be found in tutorials
included with the gwsurrogate package and in this
example
IPython code
.

NRSur4d2s_FDROM_grid12.h5 and NRSur4d2s_TDROM_grid12.h5 — These are fast
frequency-domain and time-domain (respectively) surrogate models for binary black
hole mergers where the black holes may be spinning, but the spins are restricted to
a parameter subspace which includes some but not all precessing
configurations. NRSur4d2s_FDROM_grid12.h5 is the NRSur4d2s_FDROM model described in
Blackman et al., PRD 95,
104023, (2017)
, and NRSur4d2s_TDROM_grid12.h5 is built from the underlying (slower)
NRSur4d2s time-domain model in the same way but without the FFTs. These surrogates
are also evaluated using gwsurrogate, and a tutorial can be found in this
example
IPython code
.

NRSur7dq2.h5 — This is a surrogate model for binary black hole mergers with
generic spins. A paper describing it can be foundat
Blackman et al., PRD 96,
024058 (2017)
. This surrogate is evaluated through a standalone python package contained in
NRSur7dq2.tar.gz, which has simple installation instructions in its README file. A
tutorial can be found for evaluating this surrogate in this
example
IPython code
.

If you find these surrogate models useful in your own research please cite the Field et al., PRX
(2014) paper as well as the relevant paper describing the specific numerical relativity surrogate
model, if available (e.g., the Blackman et al. 2015 paper for non-spinning binary black hole
coalescences).

Caveats:

Evaluating surrogate models outside of the ranges they were trained upon may give
inaccurate results. Please use with caution when extrapolating.

The surrogate data available here for non-spinning binary black holes produced in
Blackman et al. 2015 contains the (2,0) mode. However, this mode was not used in the
paper. While this surrogate can predict a (2,0) mode, current numerical relativity
simulations may not yet be able to accumulate (non-oscillatory) Christodoulou memory
sufficiently. The surrogate (2,0) mode is founded upon basis SpEC waveforms that have been
hybridized with leading order post-Newtonian waveforms. Therefore, the (2,0) mode can be
included in the mode’s output but should be used with caution. Currently, the default
option to evaluate this surrogate (using GWSurrogate) is to exclude all m=0 modes.
