已接受的 terminal XSherpa fit:先从 immutable saved session 纯 replot 并通过发布 guard;本页只嵌入已审计图和终态摘要。
COMPLETED;完成时间:2026-09-05T04:22:54.356875Z。模型策略:background_anchor_then_fixed_0p7_then_hot_release;初始 foreground stage 为 M31CGM sky anchor frozen; SrcApec.norm=0 frozen,保存了固定 SrcApec kT=0.7 keV 的中间 session;终端 SrcApec kT 范围为 0.5–1 keV,MWhalo kT 上限为 0.35 keV,SrcApec abundance=1 fixed。
共同合同:abundance table=angr;fit band=0.4–7.2 keV;sky area=python_float_scalar;grouping net S/N≥6、RMF FWHM oversampling≤6;MWhotHalo norm=0 frozen。
终态能谱与残差
绘图审计:51 个数据 trace,2215 个正 1σ 数据 bin,51 个 total-model trace;SP resolved/visible/fitted-zero=51/51/0;MOS lines resolved/visible=51/51。固定 0.7 keV stage 未重绘,仅作为 saved-session provenance 保留。
