收藏资源简介:
mmu_jwst_primer_uds_grizli_v6.0_all_96 HATS星表集合是多模态宇宙(Multimodal Universe)大规模天文多模态数据的一部分,具体代表詹姆斯·韦伯太空望远镜(JWST)PRIMER/UDS巡天数据的grizli v6.0处理版本。该数据集包含64,679个天文源(行)和647个特征(列),数据大小为6.1 GiB,采用HEALPix分区(11个分区)。星表列包括天文源的基本参数(如位置、通量、误差、背景、掩模等)以及多个JWST波段(如f090w、f115w、f150w、f200w、f356w、f444w等)的测光数据,用于支持大规模天文机器学习研究。数据集以Apache Parquet格式存储,可通过LSDB框架或其他工具(如pandas、pyarrow)访问。
The mmu_jwst_primer_uds_grizli_v6.0_all_96 HATS Catalog Collection is part of the Multimodal Universe, a large-scale collection of multimodal astronomical data, specifically representing the grizli v6.0 processed version of the James Webb Space Telescope (JWST) PRIMER/UDS survey data. The dataset contains 64,679 astronomical sources (rows) and 647 features (columns), with a size of 6.1 GiB, partitioned using HEALPix (11 partitions). The catalog columns include basic parameters of astronomical sources (e.g., positions, fluxes, errors, backgrounds, masks) and photometric data from multiple JWST bands (e.g., f090w, f115w, f150w, f200w, f356w, f444w), designed to support large-scale astronomical machine learning research. The dataset is stored in Apache Parquet format and can be accessed via the LSDB framework or other tools (e.g., pandas, pyarrow).
