XMM spectra of eruptions and quiescence used in the paper titled "Alive and Strongly Kicking: Stable X-ray Quasi-Periodic Eruptions from eRO-QPE2 over 3.5 Years"

The gz file has a folder containing 10 sets of spectra (two per XMMID: one using data from eruptions and one from quiescence). Each one has a corresponding rmf, arf and a background file. The files of the format: PN_Grouped_spectrumXX...fits are xspec ready. They are grouped with specgroup task of XMMSAS with mincounts=1 oversample=3. Thus, cstat is recommended while fitting in XSPEC. Alternatively, the original source spectra (PN_SPEC_SRCBKGXXX...fits) are also available so that the user can bin them as per their requirement. The background spectra have the following naming sequence: PN_SPEC_BKGXX XX = "hi" ==> eruption spectra XX = "low" ==> quiescence spectra The numbers 1...5 correspond to XMM obsIDs as follows: 1: 0872390101 2: 0883770201 3: 0893810501 4: 0932590101 5: 0932590201该gz格式压缩包内含一个目录，其中包含10组光谱数据（每个XMMID对应两组：一组基于爆发态观测数据，另一组基于静息态观测数据）。每组光谱均配有对应的响应矩阵文件（Redistribution Matrix File，RMF）、辅助响应文件（Auxiliary Response File，ARF）以及背景文件。 格式为"PN_Grouped_spectrumXX...fits"的文件可直接用于Xspec，这些文件通过XMMSAS的specgroup任务完成分组，设置参数为mincounts=1、oversample=3。因此在XSPEC中进行拟合时，推荐使用cstat统计量。 此外，还提供了原始源光谱文件（"PN_SPEC_SRCBKGXXX...fits"），用户可根据自身需求对其进行分箱处理。 背景光谱的命名规则为："PN_SPEC_BKGXX"。其中，当XX为"hi"时，对应爆发态光谱；当XX为"low"时，对应静息态光谱。 数字1至5分别对应以下XMM观测ID： 1: 0872390101 2: 0883770201 3: 0893810501 4: 0932590101 5: 0932590201
