在引力波数据中实现重心反演连续波搜索
Implementation of barycentric resampling for continuous wave searches in gravitational wave data
摘要：
我们描述了一个有效的实施相干统计连续引力波搜索从中子星。该算法的工作原理是将引力波探测器采集的数据从移动的地球坐标系转换为位于太阳系质心的坐标系。在实现该算法的过程中出现了许多实际困难，其中一些以前没有讨论过。这些困难包括限制小的计算机内存，离散的数据，损失由于插值和差距，在实际数据。这种实现方式比先前在激光干涉仪引力波（LIGO）探测器数据上的这些类型的搜索的实现方式有效得多。
英文摘要：
We describe an efficient implementation of a coherent statistic for continuous gravitational wave searches from neutron stars. The algorithm works by transforming the data taken by a gravitational wave detector from a moving Earth bound frame to one that sits at the Solar System barycenter. Many practical difficulties arise in the implementation of this algorithm, some of which have not been discussed previously. These difficulties include constraints of small computer memory, discreteness of the data, losses due to interpolation and gaps in real data. This implementation is considerably more efficient than previous implementations of these kinds of searches on Laser Interferometer Gravitational Wave (LIGO) detector data.
