摘要:

阿塔卡玛宇宙望远镜(ACT)最近发布的两个大型数据,称为DR 4和DR 5,可供公众访问。这些数据包括:在三个频带中以弧分分辨率覆盖近半个天空的温度和偏振图;覆盖~ 2,100 deg^2天空的透镜图和分量分离图;导出的功率谱和宇宙学似然性;超过4,000个星系团的目录;以及支持性的辅助产品,包括光束函数和掩模。数据和产品在一套ACT论文中进行了描述;在这里,我们提供了一个摘要。为了方便访问这些数据,我们提供了一组IPython Notebook,旨在向用户介绍DR 4、DR 5以及分析这些数据所需的工具。数据产品(不包括模拟)和一套笔记本电脑是公开的美国宇航局微波背景数据分析(LAMBDA)的遗产档案;模拟产品可在国家能源研究科学计算中心(NERSC)。

英文摘要:

Two recent large data releases for the Atacama Cosmology Telescope (ACT), called DR4 and DR5, are available for public access. These data include temperature and polarization maps that cover nearly half the sky at arcminute resolution in three frequency bands; lensing maps and component-separated maps covering ~ 2,100 deg^2 of sky; derived power spectra and cosmological likelihoods; a catalog of over 4,000 galaxy clusters; and supporting ancillary products including beam functions and masks. The data and products are described in a suite of ACT papers; here we provide a summary. In order to facilitate ease of access to these data we present a set of Jupyter IPython notebooks developed to introduce users to DR4, DR5, and the tools needed to analyze these data. The data products (excluding simulations) and the set of notebooks are publicly available on the NASA Legacy Archive for Microwave Background Data Analysis (LAMBDA); simulation products are available on the National Energy Research Scientific Computing Center (NERSC).
