我们提出了一个七波段（g、r、i、z、y、NB816、NB921）目录，该目录源自斯巴鲁 Hyper Suprime-Cam（HSC）对北黄道极（NEP）的成像调查。这项名为 HEROES 的巡天由 44 deg2 的连续成像组成，深度达到中值 5σ，g: 26.5、r: 26.2、i: 25.7、z: 25.1、y: 23.9、NB816: 24.4 和 NB921: 24.4 mag。我们使用 HSC 管道软件 hscPipe 减少了这些数据，并生成了包含超过 2500 万个对象的多频段目录。我们提供三种格式的目录：(1) hscPipe 格式强制光度测定目录的集合，(2) 包含该数据集中的每个对象以及选定的有用列的单个组合目录，以及 (3) 组合目录的较小变体，仅包含用于基本分析或低内存机器的基本列。该目录使用 NEP 上所有可用的 HSC 数据，并且可以作为 SCUBA-2、eROSITA、Spitzer、Euclid 和 JWST 等仪器和天文台当前和未来 NEP 深场的主要光学目录。
We present a seven-band (g, r, i, z, y, NB816, NB921) catalog derived from a Subaru Hyper Suprime-Cam (HSC) imaging survey of the North Ecliptic Pole (NEP). The survey, known as HEROES, consists of 44 deg2 of contiguous imaging reaching median 5σ depths of g: 26.5, r: 26.2, i: 25.7, z: 25.1, y: 23.9, NB816: 24.4, and NB921: 24.4 mag. We reduced these data with the HSC pipeline software hscPipe, and produced a resulting multiband catalog containing over 25 million objects. We provide the catalog in three formats: (1) a collection of hscPipe format forced photometry catalogs, (2) a single combined catalog containing every object in that data set with selected useful columns, and (3) a smaller variation of the combined catalog with only essential columns for basic analysis or low-memory machines. The catalog uses all the available HSC data on the NEP and may serve as the primary optical catalog for current and future NEP deep fields from instruments and observatories such as SCUBA-2, eROSITA, Spitzer, Euclid, and JWST.
