这是RIT数值相对论黑洞双星波形公开目录的第四版url{http：//ccrg.rit.edu/RITCatalog}，包含1881个精确的模拟，其中包括446个进动和611个非进动的准圆/吸气双星系统，质量比在1/128 leq qleq 1 $范围内，单个自旋高达$s/m^2=0.95$; 824个偏心轨道在0 <leq 1 $范围内。该目录还提供了双星的初始参数，轨道信息，峰值辐射和最终的残余黑洞属性。对波形进行质心漂移校正，并外推到未来的零无穷大。作为此波形目录的应用程序，我们重新分析所有的峰值辐射和残余物的属性，以找到新的，简单的，它们之间的相关性，有效的偏心率的存在下，实际天体物理学的使用。
This fourth release of the RIT public catalog of numerical relativity black-hole-binary waveforms url{http://ccrg.rit.edu/~RITCatalog} consists of 1881 accurate simulations that include 446 precessing and 611 nonprecessing quasicircular/inspiraling binary systems with mass ratios $q=m_1/m_2$ in the range $1/128leq qleq1$ and individual spins up to $s/m^2=0.95$; and 824 in eccentric orbits in the range $0<eleq1$. The catalog also provides initial parameters of the binary, trajectory information, peak radiation, and final remnant black hole properties. The waveforms are corrected for the center of mass drifting and are extrapolated to future null infinity. As an application of this waveform catalog we reanalyze all of the peak radiation and remnant properties to find new, simple, correlations among them, valid in the presence of eccentricity, for practical astrophysical usage.
