Data Analysis
How will data be analyzed on my computer?
The two LIGO detectors and GEO 600 each have their own large collection of data. In order to sort through all of this data and find gravitational wave signals, the data has to be broken into small sets that can be processed by individual computers.
Each computer gets data corresponding to a specific area of sky and a specific time interval. Each computer also gets a model of what scientists think a pulsar signal from that part of the sky should look like in the data. Pulsar signals are expected to be sine waves, like the one shown below.
数据分析
在我的电脑上是如何分析数据的?
两个LIGO探测器和GEO 600,每个都有他们自己的数据集合。为了将所有的这些数据分类,从而发现引力波信号,数据要被分成可以被个人计算机处理的小集合。每个计算机分配到指定的天空区域和指定的时间间隔的数据,每个计算机也被分配到那些在指定的天空区域内,被科学家们认为是脉冲星信号的模型,该模型也应该被看作是数据。脉冲星信号应该被看作是正弦波,如下图所示。
A sine wave is the graph of the equation y = sin x. A sine wave has the same amplitude (distance from centerline to the top of a peak) and wavelength (distance from peak to peak) over time.
A wave that repeats, like the one above, is called a periodic wave. In addition to amplitude and wavelength, a periodic wave is characterized by its frequency. The frequency of a wave is the number of wavelengths that pass a given point in one second. Gravitational waves signals look like sine waves and occur at different frequencies that depend on their source.
一个正弦波是等式y=sinx的曲线图。一个正弦波有相同的振幅(从中心线到上方顶点的距离)和波长(是在一个周期内从顶点到顶点的距离)。
波象上图所示是重复的,被称为周期波。除了振幅和波长,周期波有它自己的频率。波的频率是波长的数量是在一秒中内通过一个给定的点。引力波信号看起来象正弦波,但根据他们自己的震源有不同的频率。
