The RIT numerical relativity group is releasing the second public catalog of black-hole-binary waveforms \url{this http URL}. This release consists of 320 accurate simulations that include 46 precessing and 274 nonprecessing binary systems with mass ratios $q=m_1/m_2$ in the range $1/6\leq q\leq1$ and individual spins up to $s/m^2=0.95$. The new catalog contains search and ordering tools for the waveforms based initial parameters if the binary, trajectory information, peak radiation, and final remnant black hole properties. The waveforms are extrapolated to infinite observer and can be used to independently interpret gravitational wave signals from laser interferometric detectors. As an application of this waveform catalog we reanalyze the signal of GW150914 using parameter estimation techniques that make use of only numerical waveforms without any use of information from phenomenological models. The final black hole remnant properties provided here can be used to model the merger of black-hole binaries from its initial configurations.
