本文档描述了Ligo算法库(LAL)中新的数值相对性(NR)注入基础结构,因此,该基础结构允许将NR波形用作LAL中的离散波形大约用作NR波形。使用此新界面,以所述格式提供的NR波形可以直接用作模拟GW信号(“注射”),以进行数据分析,其中包括参数估计,搜索,硬件注射等,而不是先前的基础架构,此新界面本地处理从进攻二进制黑洞的数值模拟中处理子主导模式和波形,使它们可以直接访问Ligo分析。为了正确处理进攻模拟,新的NR注入基础架构内部将NR数据转换为LAL中使用的坐标框架约定。
This document describes the new Numerical Relativity (NR) injection infrastructure in the LIGO Algorithms Library (LAL), which henceforth allows for the usage of NR waveforms as a discrete waveform approximant in LAL. With this new interface, NR waveforms provided in the described format can directly be used as simulated GW signals ("injections") for data analyses, which include parameter estimation, searches, hardware injections etc. As opposed to the previous infrastructure, this new interface natively handles sub-dominant modes and waveforms from numerical simulations of precessing binary black holes, making them directly accessible to LIGO analyses. To correctly handle precessing simulations, the new NR injection infrastructure internally transforms the NR data into the coordinate frame convention used in LAL.
