M31 run6 MOS spectrum atlas
中文Receipt-backed v1.6.1 MOS products from m31_v161_20260830_run6_partial1: all available ObsIDs aggregated per region, plus a separate static spectrum page for each available ObsID×region.
xsherpa.inspect.SpectrumInspector. Each uses PHA + paired ESAS QPB + ARF + RMF; QPB is subtracted before grouping, which is net S/N ≥ 6 with RMF FWHM oversampling ≤ 6. No model was created, no fit performed, and no physical parameters or scientific conclusions were produced.Display range 0.3–7.2 keV, y-axis is ARF-unfolded sb_flux. The MOS fit-excluded band 1.4–2.0 keV is neither interpreted nor fit here; it remains a visible energy channel of the inspection spectrum.

The static site publishes only derived PNGs and cleaned metadata; raw PHA/QPB/ARF/RMF, absolute data paths, and observation event files are not published.
Joint-fit results
51 MOS spectra; includes all-ObsID data, best-fit model, components and Δχ residuals; no SrcApec.
Radial XSherpa inspect comparison
One annulus, one color, graded from inside to outside; all ObsID/MOS cameras shown independently, neither fit nor combined.
Direct-data band-flux profile
QPB-subtracted, ARF/RMF response-unfolded, per-spectrum direct measurements normalized by sky area; no physical model or fit.
SrcApec six-way joint fit
Each provides all-ObsID data, best-fit model/components and Δχ with errors; MWhotHalo=0, SrcApec included.
All elliptical-annulus SrcApec fits
20 accepted terminal fits, all pure replots, with all-ObsID spectra, model components, SP/MOS lines and Δχ on detail pages; a=128–144′ explicitly retained as having no usable MOS spectra and not fit.
All elliptical-annulus profile overview
Pure-data radial plots for all published annuli, the 0.4–1.4 keV quality table, and the current complete 8′ no-BKG parameter profile on one page; the error definition and excluded range of each metric are explicitly marked.
