This repository contains all publicly available SACRA gravitational waveforms for binary neutron star mergers. All the waveforms for Ψ_{4} are provided at several fixed extraction radii and those for h are extrapolated to future null infinity. For all the runs, waveforms are provided at 6 grid resolutions, e.g., N=182, 150, 130, 110, 102, and 90. N=182 is a higher resolution than N = 90.

- All the waveforms are provided with c=G=M
_{sun}=1 unit. - All the waveforms are provided for the l=2, m=2 mode.

The data in this catalog are free for anyone to use, but we request that you please acknowledge the first scientific publication of each simulation.
We may provide the simulation data for the ejecta, the remnant, and etc. Please contact to the first author of the corresponding papers.

Ψ_{4} data are provided with file names in the format of psi4_*_l2m2, where * denotes the extraction radius in the unit of M_{sun}.

Data are contained in files in the next format:

h data are provided with file names in the format of h_*l2m2, where * denotes the extraction radius in the unit of M_{sun}. h is calculated from Ψ_{4} data employing fixed frequency method [1] and are extrapolated to future null infinity employing the method of [2] (please see arxiv:1708.08926, 1802.06518, or 1907.03790 for more details).

Data are contained in files in the next format:

Here, D is an approximate proper area of the extraction radius (please see arxiv :1907.03790 for more details).
