论文摘要
CMB研究中系统错误的最重要检查之一是独立实验制作的地图的跨相关性。在本文中，我们报告了Atacama B模式搜索（ABS）和Atacama Cosmology望远镜（ACT）实验的跨相关性。这些完全不同的测量值与$ \ ell <400 $相同的EE和TE Spectra中的Planck卫星都具有明显的相关性，而大约$ 1100 $ deg $^2 $共有这三个$。 TB，EB和BB跨光谱与噪声一致。利用这种互相关对于智利运营的未来实验至关重要，旨在调查$ 30 <\ ell <8,000美元的范围。
One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correlation between maps from the Atacama B-mode Search (ABS) and Atacama Cosmology Telescope (ACT) experiments in both temperature and polarization. These completely different measurements have a clear correlation with each other and with the Planck satellite in both the EE and TE spectra at $\ell<400$ over the roughly $1100$ deg$^2$ common to all three. The TB, EB, and BB cross spectra are consistent with noise. Exploiting such cross-correlations will be important for future experiments operating in Chile that aim to probe the $30<\ell<8,000$ range.
