mmu_jwst_gds HATS目录集合是一个天文数据集，属于多模态宇宙项目的一部分，基于詹姆斯·韦伯太空望远镜（JWST）NIRCam的早期深场观测。数据集包含固定大小的图像切块（96×96像素），中心来自测光目录的源，图像是多波段的，具有6或7个滤镜，覆盖波长从约0.9μm到4.4μm。数据以HATS目录格式存储，使用Apache Parquet数据集，包含17,494行和11列，总大小约6.3 GiB。典型用例包括科学出版物和机器学习应用。注意事项：不同调查的波长覆盖可能不同，缺失波段用零数组表示以简化数据加载。数据来自Dawn JWST Archive (DJA)。

The mmu_jwst_gds HATS Catalog Collection is an astronomical dataset part of the Multimodal Universe project, based on James Webb Space Telescope (JWST) NIRCam observations from early deep field surveys. It consists of fixed-size image cutouts (96×96 pixels) centered on sources from photometric catalogs, with multi-band images covering 6 or 7 filters across wavelengths from approximately 0.9μm to 4.4μm. The data is stored in HATS catalog format as an Apache Parquet dataset, containing 17,494 rows and 11 columns, with a total size of about 6.3 GiB. Typical use cases include scientific publications and machine learning applications. Caveats: Different surveys have varying wavelength coverage, and missing bands are represented as arrays of zeros to simplify data loading. The data is sourced from the Dawn JWST Archive (DJA).
