标题： Parameter estimation of neutron star-black hole binaries using an advanced gravitational-wave detector network: Effects of the full post-Newtonian waveform

摘要： 我们研究了在提取来自合并致密双星（CCB）系统的吸积信号参数时，使用{\it 完整}波形（FWF）相对于传统{\it 限制的}波形（RWF）的影响，利用第二代干涉探测器的全球网络。 我们通过采用完整的后牛顿波形，研究了一个假设的(1.4-10)$M_\odot$NS-BH 双星群体（在天空中均匀分布且取向一致）。这些波形不仅包括除主导项（四极模）以外的各种谐波贡献，还包括与每个谐波相关的后牛顿振幅修正，这些是该系统预期的吸积信号。 预计由两个LIGO探测器和一个Virgo探测器组成的引力波探测器网络将加入KAGRA和计划中的LIGO-India。 我们研究了所有16种可能的探测器配置下的参数估计问题。 比较使用FWFs和使用RWFs（仅包含主导谐波的牛顿振幅贡献）获得的误差分布中位数，我们发现对于光度距离和倾斜角余弦的测量精度几乎提高了1.5-2倍，具体取决于所考虑的网络。 尽管使用FWF不会显著提高源定位精度，但由五个探测器组成的全球网络相比使用3探测器的LIGO-Virgo网络，在同一波形模型下，源定位精度将提高4倍。 显示英文摘要

摘要： We investigate the effects of using the {\it full} waveform (FWF) over the conventional {\it restricted} waveform (RWF) of the inspiral signal from a coalescing compact binary (CCB) system in extracting the parameters of the source, using a global network of second generation interferometric detectors. We study a hypothetical population of (1.4-10)$M_\odot$ NS-BH binaries (uniformly distributed and oriented in the sky) by employing the full post-Newtonian waveforms, which not only include contributions from various harmonics other than the dominant one (quadrupolar mode) but also the post-Newtonian amplitude corrections associated with each harmonic, of the inspiral signal expected from this system. It is expected that the GW detector network consisting of the two LIGO detectors and a Virgo detector will be joined by KAGRA and by proposed LIGO-India. We study the problem of parameter estimation with all 16 possible detector configurations. Comparing medians of error distributions obtained using FWFs with those obtained using RWFs (which only include contributions from the dominant harmonic with Newtonian amplitude) we find that the measurement accuracies for luminosity distance and the cosine of the inclination angle improve almost by a factor of 1.5-2 depending upon the network under consideration. Although the use of FWF does not improve the source localization accuracy much, the global network consisting of five detectors will improve the source localization accuracy by a factor of 4 as compared to the estimates using a 3 detector LIGO-Virgo network for the same waveform model.
