随着未来观测时间的增加, 我们能探测到更低频的背景, 而且引力波信号的信噪比也会相应增加. 当观测时间长于木星、土星的公转周期时, 由太阳系星历表(Solar system ephemeris)带来的误差会被进一步降低. 另一方面, 随着设备的升级以及校准方法的提升, 可以在更高的计时精度上看到更多的...
http://projects.astro.illinois.edu/data/Retrograde/index.htmlAround 150 A.D. the astronomer Ptolemy resolved this problem by using a system of circles to describe the motion of planets (Figure below). In Ptolemy’s system, a planet moves in a small circle, called an epicycle. This circle...
