ACT-PLANCK DR4DR6 map healpix U survey collection

This is the U component of a low-resolution map representing a weighted average of the f090 and f150 linear polarization. For a slightly deeper map, we combined the DR4 based on...本数据集为低分辨率天图的U分量（U component），该天图表征了f090与f150波段线偏振信号的加权平均结果。针对深度稍深的天图，我们基于……结合了第四批数据发布（DR4，Data Release 4）的相关数据。
