Parameter candidates identical across the two MOS2 observations.
Dual-observation
Al line-contrast–GTI Pareto · r23
The same strategy set and the same Al line-to-continuum definition are applied simultaneously to the flare-rich 0800730101 MOS2 and the near-stable 0800730201 MOS2. r8–r23 test, in order, multi-scale/local baselines, line-anchored × high-band hybrid, episode closure, sustained core/shoulder, finite-time-window alignment, pure FOV CUSUM, corner-scaled CUSUM, dual CUSUM confirmation, symmetric line-window widths, low-FOV alpha calibration, local scaled-excess, and the alpha sensitivity of scaled-residual Bayesian Blocks; the goal is to push 0101 toward the upper right while keeping 0201 at least 95% of its GTI.

gti_fraction ≥ 0.95; the page then takes the joint frontier on the 0800730101 Al line-contrast–GTI plane accordingly. Only a strategy that has both 0101 Al/continuum contrast gain and enough GTI, and does not cut 0201 below 95%, is worth entering subsequent matched 4.background and XSherpa validation.3398 / 4706

First pass 0201 ≥95%, then select toward the upper right on 0101.
L_Al/C = Al-K sideband-excess / [rate(1.00–1.40 keV) + rate(1.85–2.00 keV)]; the y-axis is 100×[(L_Al/C)_strategy/(L_Al/C)_2.filter−1], with error bars from nested-PHA Gehrels delta-method errors. It is a detector-space screening metric, not a fitted line flux, SP flux, or calibrated photon flux. The broadband Q = rate(1.4–1.8)/[rate(1.0–1.4)+rate(1.8–3.2)] serves only as a concordance control in the table. Solid points mean 0201 retains ≥95%; open points mean they cross this guardrail.
R_FOV−alpha R_corner is screened. The r22 Blocks act only on that correctly scaled residual, and are segmented by Gaussian-measurements Bayesian Blocks within each original 2.filter live run; they are not Blocks of the raw FOV rate, nor a Poisson two-component SP fit.sym 4.5, 75-s, p0=0.05, q=0.25, z=2, 15-s padding gives 0101 99.08%, Al +0.72±1.15%, and 0201 100.00%, Al 0.00±1.39%. r23 only extends the low-FOV alpha calibration of the same Blocks rule to 0.35/0.50: of the 320 new points passing control, 35 numerically distinct coordinates are all dominated by the existing frontier, and the rest are equivalent reproductions of existing GTI. So alpha sensitivity did not continue to raise the boundary. r22's small step only connects/refines the existing frontier on point estimates, with amplitude under one statistical error, still not an SP detection.Currently most useful joint candidates
The table below is not a final recommendation list, but representative points for deciding the next round of matched spectral extraction. Al-rate retention is a protective cross-check of the primary coordinate: it should be consistent with 0; 0201's Al and broadband Q should also be consistent with 0. The hybrid consensus version retains time accepted by either selector; the conservative version retains only time accepted by both.
