UPdec-Webb
收藏资源简介:
UPdec-Webb数据集是由中国科学院紫金山天文台创建的,用于处理詹姆斯·韦伯太空望远镜(JWST)的近红外相机(NIRCam)图像叠加的数据集。该数据集包含45条数据,涵盖了SMACS J0723星系团的图像数据。数据集通过应用UPDC算法,解决了点扩散函数(PSF)效应,提供了视觉上增强和更清晰的图像。数据集的创建过程包括图像校正、星系团内光处理和JWST PSF重建等步骤。该数据集主要应用于天文学领域,旨在提高对遥远天体的高分辨率成像和光度测量的准确性。
The UPdec-Webb dataset was constructed by the Purple Mountain Observatory, Chinese Academy of Sciences, specifically for processing co-added Near-Infrared Camera (NIRCam) images from the James Webb Space Telescope (JWST). This dataset comprises 45 entries covering image data of the SMACS J0723 galaxy cluster. By applying the UPDC algorithm, it mitigates the point spread function (PSF) effect, producing visually enhanced and significantly sharper images. The dataset construction workflow includes multiple steps such as image correction, intra-cluster light processing, and JWST PSF reconstruction. Primarily applied in the field of astronomy, this dataset aims to improve the accuracy of high-resolution imaging and photometric measurements for distant celestial bodies.
