中文摘要：
我们在我们的以前的工作发现了那不同观察 systematics ，例如从天线指的错误，在态度和科学数据之间的方向或异步可以在宇宙的微波背景( CMB )的完整天空的地图产生一个伪偶极子信号被威尔金森微波 Anisotropy 探查( WMAP )队出版了的 anisotropy 。我们发现了对 Doppler 信号的天线 sidelobe 反应生产类似的效果。在这个工作，从来源独立，我们一致地为伪偶极子信号建模并且由模型适合把它从出版 WMAP7 CMB 地图移开。结果证明释放 WMAP CMB 四极是几乎完全人工的。
英文摘要：
We have discovered in our previous work that different observational systematics, e.g. errors from antenna pointing directions or an asynchronism between the attitude and science data may generate a pseudo-dipole signal in the full-sky maps of the cosmic microwave background （CMB） anisotropy that have been published by the Wilkinson Microwave Anisotropy Probe （WMAP） team. We have found that the antenna sidelobe response to the Doppler signal produces a similar effect. In this work, independent from the sources, we have uniformly modeled the pseudo-dipole signal and have removed it from the published WMAP7 CMB maps by model fitting. The result demonstrates that the released WMAP CMB quadrupole is almost completely artificial.
