在后牛顿近似下，用两个质量相当的旋转致密天体旋转双星的绝热激发过程中发射的引力波形，可以通过将两个自旋中的一个设置为零而相当准确地再现，至少为了地面引力波干涉仪的探测目的。在这里，我们提出用这个准物理族的单自旋模板族来寻找双自旋过程双星发出的信号，我们发现它的信号匹配性能对于源质量(m{sub1}，m{sub2})是[3，15]M{sub{center_dot}}x[3，15]M{sub{center_dot}}的成员。对于这个质量范围，使用LIGO-I设计灵敏度，我们估计产生最小匹配0.97所需的模板数量为{约}320,000。我们还讨论了单自旋模板族可以用来估计原始双自旋进动双星参数的精度。
The gravitational waveforms emitted during the adiabatic inspiral of precessing binaries with two spinning compact bodies of comparable masses, evaluated within the post-Newtonian approximation, can be reproduced rather accurately by the waveforms obtained by setting one of the two spins to zero, at least for the purpose of detection by ground-based gravitational-wave interferometers. Here we propose to use this quasiphysical family of single-spin templates to search for the signals emitted by double-spin precessing binaries, and we find that its signal-matching performance is satisfactory for source masses (m{sub 1},m{sub 2}) is a member of [3,15]M{sub {center_dot}}x[3,15]M{sub {center_dot}}. For this mass range, using the LIGO-I design sensitivity, we estimate that the number of templates required to yield a minimum match of 0.97 is {approx}320,000. We discuss also the accuracy to which the single-spin template family can be used to estimate the parameters of the original double-spin precessing binaries.
