X-ray spectra for galaxy or galaxy group in a Chandra observation of MACS J0717.5+3745

These are the data files needed to follow along with the spectral analysis I do to determine the physical processes causing the emission from the galaxy, or group of galaxies, at RA=7h 16m 44.3s and Dec=+37d 39' 56'' (J2000), from the Chandra observation of the galaxy cluster MACS J0717.5+3745 (the cluster and group are physically unrelated).

本数据集收录了复现笔者所开展的光谱分析工作所需的全部数据文件：该分析旨在探明位于赤经（Right Ascension，RA）7h16m44.3s、赤纬（Declination，Dec）+37°39′56″（J2000坐标系）的单个星系或星系群的辐射起源物理机制，相关观测数据取自钱德拉（Chandra）X射线天文台对星系团MACS J0717.5+3745的观测成果。需说明的是，该星系团与前述星系群物理上互不关联。
