We distribute complete gravitational-wave signals in the Advanced LIGO band (10 Hz - 8192 Hz) of the inspiral and merger of two neutron stars. These waveforms been constructed by hybridizing numerical-relativity data obtained with the WhiskyTHC code [1] with tidal effective-one-body waveforms [2,3]. More details on the procedure used to generate these waveforms are given in [4]. The waveforms are distributed as HDF5 files containing the amplitude and phase of the -2 spin-weighted spherical harmonics multipoles of the strain: \(( h_+ - \mathrm{i} h_\times )_{l,m} = \frac{A_{l,m}}{D_{\rm cm}} \exp(-\mathrm{i} \phi_{l,m} )\) where \(D_{\rm cm}\) is the distance in cm from the source. The data files include a machine readable "/metadata" group with: /metadata/EOS: name of the equation of state /metadata/M_{A|B}: mass in isolation of star A (or B) in grams /metadata/R_{A|B}: radius of star A (or B) in cm /metadata/k2T: tidal coupling constant of the binary (see [3]) /metadata/kl_{A|B}: l=2,3,4 dimensionless Love numbers of star A (or B) We store amplitude and phase for multipoles modes up to l=4 as time series sampled at 16384 Hz. We make these waveforms freely available in the hope that they will be useful. We kindly ask you to cite [3] and [4] in any publication resulting from the use of these waveforms. --- [1] http://www.tapir.caltech.edu/~david_e/whiskythc.html [2] https://eob.ihes.fr/ [3] S.
