这是什么项目? XMM-Newton 望远镜每次观测都会被软质子 (soft proton) 耀斑污染，必须用"好时间段 (good time interval, GTI)"把耀斑时间删掉。删多删少是一对矛盾：多删 → 剩下的数据更干净但更少；少删 → 数据多但更脏。ParetoGTICal 把这个取舍当作一个帕累托问题 (Pareto problem):在单次观测内部，用保留活时间 f_T 与连续谱约减因子 R = C_all/C_K 两个坐标给每个候选 GTI 打分，并用 Al-K、Si-K 荧光线的不变性做门 (gate),防止"挑噪声"伪装成"删耀斑"。它属于父项目 DiffuseXrayCalibration （校准 XMM EPIC 弥散发射分析），但有自己的问题、自己的认知操作系统 (cognition OS) 和自己的预注册 (pre-registration) 纪律。

What is this project? Every XMM-Newton observation is polluted by soft-proton flares, and "bad" time must be removed by keeping only good time intervals (GTIs). How much to cut is a genuine conflict: cut more and the retained data are cleaner but fewer; cut less and there are more data but dirtier ones. ParetoGTICal treats this trade-off as a Pareto problem: within one observation, every candidate GTI is scored by two coordinates — retained live time f_T and the continuum reduction factor R = C_all/C_K — with an Al-K / Si-K fluorescence-line stability gate that stops "selecting noise" from masquerading as "cutting flares". It is a sub-project of DiffuseXrayCalibration (calibrating the XMM EPIC diffuse-emission analysis), with its own question, its own cognition OS and its own pre-registration discipline.

四个问题，一屏作答Four questions, answered on one screen

现在在哪？
Where does it stand?: P001 已关闭（D006），答案否定：等保留率下率排名在任何主集上都不优于 2.filter。此后项目转向 误差预算判据 (C001)：多观测时一致性比信噪比重要。P002 F1（Al 线是否跟随角落粒子水平）只在 CDFS MOS2 上成立(b = 1.015 ± 0.030,TRACKS),其余三个集都是 b ≈ 0.6–0.7（INTERMEDIATE）。C1b（2.filter 内的不相交能段裁剪）在已消费数据上把观测内系统误差减半：12% → 5–6%（100 s cell），代价 20–26% 活时间。; P001 is closed (D006), negative: at equal retention rate-rank does not beat 2.filter on any primary set. The project then turned to the error-budget criterion (C001): over several observations, consistency matters more than S/N. P002 F1 (does the Al line track the corner particle level?) holds on CDFS MOS2 only (b = 1.015 ± 0.030, TRACKS); the other three sets all give b ≈ 0.6–0.7 (INTERMEDIATE). C1b (a disjoint-band clip inside 2.filter) halves the within-observation systematic on consumed data: 12% → 5–6% (100 s cells) for 20–26% of live time.
还有什么没解决？
What is unsolved?: ① 为什么 CDFS MOS2 以外的三个集都是 b ≈ 0.6–0.7（P002 F1 复制失败，原因未测）;② 100 s cell 上约 5% 的快速"白"残差从哪来（裁剪后仍在，不跟随角落，会从任何谱中平均掉）;③ 谱验证 (C2) 还没做 —— C001 的快速判据最终要用光谱一致性检验。; ① Why do the three sets other than CDFS MOS2 all give b ≈ 0.6–0.7 (the P002 F1 replication fails; causes untested); ② the origin of the ~5% fast residual at 100 s cells (it survives the clip, does not follow the corner, and averages out of any spectrum); ③ spectral validation (C2) is still to come — C001's quick criterion must finally be checked against spectral consistency.
接下来做什么？
What do I do next?: 按 PI 顺序（D011/D012）:(a) 冻结 C1b 滤波器已完成（H,B = 300 s,n = 1,在 2.filter 之内;打分 cell 尺寸已定 1000 s,Claude 受 PI 委托用实验选定）;（b) 一次新的 Lockman Hole 还原，同时检验 P002 F2 与冻结后的滤波器（派发时间由 PI 决定，不预设日期）;（c) P002 之后做 C2 谱验证。步骤格式见"如何接手"页 §5。; In the PI's order (D011/D012): (a) the C1b filter is frozen (H, B = 300 s, n = 1, inside 2.filter; the scoring cell size is set to 1000 s, chosen by Claude by experiment under the PI's delegation); (b) one fresh Lockman Hole reduction, testing both P002 F2 and the frozen filter (dispatched later by the PI's decision; no date invented); (c) C2 spectral validation after P002.

E3 fails on every primary set; the CDFS gain is consistent in sign but only about 0.3% (descriptive). Corner: usable on CDFS, too noisy on M31 MOS1. `results/p001_m31_mos1/p001_endpoints_m31.json`; `results/p001_cdfs/p001_endpoints_all.json`; `cognition-os/experiments/E002_p001_m31_mos1.md`; `E003_p001_cdfs_blank_field.md`	→
3	定义下游成功判据Define the downstream success criterion	已定义（C001 v2），验证待 C2DEFINED (C001 v2); validation awaits C2	判据 = 误差预算（D007/D008）：单观测 σ_tot = σ_stat ⊕ ε·C_K；多观测先看一致性（拼接光变曲线的 s_sys，不随观测数下降），σ_tot,set = s_sys ⊕ 1/√N_counts。实测（2.filter,0.5–2 keV）：s_sys = 17–25%（观测内 11–13%、观测间 12–22%），而 s_stat 只有 0.04–0.2% —— 系统误差约是统计误差的 100 倍。C1 角落项把观测间部分从 ~12% 降到 3–4%；C1b 把观测内部分从 12% 减到 5–6%（100 s）。打分 cell 尺寸已定：1000 s（D012,Claude 受 PI 委托实验选定）；1000 s 上角落修正后 CDFS s_sys：2.filter 8.4%/8.0%、裁剪 3.7%/3.2%（MOS2/MOS1）。The criterion is the error budget (D007/D008): single observation σ_tot = σ_stat ⊕ ε·C_K; over a set, consistency comes first (the concatenated-light-curve s_sys, which does not fall with the number of observations), σ_tot,set = s_sys ⊕ 1/√N_counts. Measured (2.filter, 0.5–2 keV): s_sys = 17–25% (within 11–13%, between 12–22%) against s_stat of only 0.04–0.2% — the systematic is about 100× the statistical. The C1 corner term takes the between part from ~12% to 3–4%; C1b halves the within part from 12% to 5–6% (100 s). The scoring cell size is now set: 1000 s (D012, chosen by Claude by experiment under the PI's delegation); at 1000 s the corner-corrected CDFS s_sys is 8.4%/8.0% for 2.filter and 3.7%/3.2% for the clip (MOS2/MOS1). `prereg/C001_error_budget_criterion.md` §2/§2b/§3b/§3c/§3d/§3e; `results/c001_concat/c001_concat.json`; `results/c001_concat/c001_c1_corner_corrected.json`; `results/c001_c1b/c001_c1b.json`; `results/c001_cellsize/c001_cellsize.json`; `04_DECISION_LOG.md` D012	↗

Per §6, "the Al line is a particle monitor" is not established in general; F2 (within observations) waits for the Lockman Hole. F3: on CDFS MOS2 the line follows Q between observations but not within them — pointing to a K/B systematic in the line measurement (the T005 disposition). `prereg/P002_al_line_vs_corner.md` §9; `results/p002/p002_f1_cdfs.json`; `results/p002/p002_f1_m31.json`; `cognition-os/experiments/E004_p002_al_vs_corner.md`	→

It also sees a real K/B particle-level difference on CDFS: rejected time has a 1.9% (MOS1, −4.3σ) and 3.9% (MOS2, −10σ) higher corner 2.5–8 keV rate. New open sub-question (not pre-registered): the corner's particle-level change does not carry into the as-gated Al-line ratio. `results/p001_cdfs/p001_endpoints_all.json` (E5); `03_TRUST_TABLE.md` T017; `E003_p001_cdfs_blank_field.md` §Reading 3§Reading 3	→

R 筛选在等保留率下是否优于归档 2.filter?Does the R screen beat the archived 2.filter at equal retention?	这是 P001 的主要终点；若不优于，方法的全部价值就只剩"选保留率"这一层。This was P001's primary endpoint; if not, the method's whole value reduces to "choosing a retention".	不优于（已关闭）：四个主集的 E3 全部失败 —— M31 MOS1 13/25（Z = 0.02）、M31 MOS2 21/29（Z = 1.64）、CDFS MOS1 24/29（Z = 1.55）、CDFS MOS2 27/29（Z = 1.73）。CDFS 上符号一致但增益约 0.3%，远低于 Z > 3;按 D7 记"持平"。Not better (closed): E3 fails on all four primary sets — M31 MOS1 13/25 (Z = 0.02), M31 MOS2 21/29 (Z = 1.64), CDFS MOS1 24/29 (Z = 1.55), CDFS MOS2 27/29 (Z = 1.73). On CDFS the sign is consistent but the gain is about 0.3%, far below Z > 3; "no significant difference" under D7.	已由 CDFS 盲测完成（E003）：证据收据 `p001_endpoints_all.json`。问题关闭。Done by the CDFS blind run (E003); receipt `p001_endpoints_all.json`. The question is closed.	T019 / 在 M31 与 CDFS 上被驳倒REFUTED on M31 and CDFST019 / REFUTED on M31 and CDFS
Al 线是否跟随角落粒子水平？(P002 F1/F2)Does the Al line track the corner particle level? (P002 F1/F2)	若跟随，P001 线门（L_K = L_B）就要允许 L_K/L_B = Q_K/Q_B;若不跟随，线门成立。这决定线门作为粒子锚是否可信（T005/T016）。If it tracks, the P001 line gate (L_K = L_B) must allow L_K/L_B = Q_K/Q_B; if not, the gate stands. This decides whether the line gate is a trustworthy particle anchor (T005/T016).	F1 已答（E004）：CDFS MOS2（主集）b = 1.015 ± 0.030 → TRACKS,横跨 2.2 倍的 Q 范围（2001–2019）;其余三集 b = 0.588 ± 0.020、0.602 ± 0.070、0.694 ± 0.050 → INTERMEDIATE。按 §6 未在一般意义上确立。F3：CDFS MOS2 观测之间跟随、观测之内不跟随 → 线测量里的 K/B 系统误差（T005）。F1 is answered (E004): CDFS MOS2 (primary) b = 1.015 ± 0.030 → TRACKS across a factor-2.2 range in Q (2001–2019); the other three sets give 0.588 ± 0.020, 0.602 ± 0.070, 0.694 ± 0.050 → INTERMEDIATE. Per §6, not established in general. F3: on CDFS MOS2 the line follows Q between observations but not within them → a K/B systematic in the line measurement (T005).	F2（观测之内）等一次新的 Lockman Hole 还原（派发由 PI 决定）;b ≈ 0.6–0.7 的成因需要自己的预注册（未测：MOS1 几何与 CCD 损失、M31 天空 1.49 keV 贡献、短杠杆臂、不激发 Al 的 Q 分量）。F2 (within observations) waits for one fresh Lockman Hole reduction (dispatched by the PI); the causes of b ≈ 0.6–0.7 need their own pre-registration (untested: MOS1 geometry and CCD losses, an M31 sky contribution at 1.49 keV, the short lever arm, and a Q component that does not excite Al).

C1b 滤波器在新场上成立吗？Does the C1b filter hold on a fresh field?	C1b 是把 GTI 从"删耀斑"升级为"压观测内系统误差"的第一个具体候选；若在 Lockman Hole 上复现，C001 的 ~2% 目标（≥ 1000 s）就有一个可冻结的滤波器。C1b is the first concrete candidate that upgrades the GTI from "cutting flares" to "suppressing the within-observation systematic"; if it replicates on the Lockman Hole, C001's ~2% target (≥ 1000 s) gets a freezable filter.	在已消费的 CDFS 与 M31 上成立（T023,探索性）：观测内 11.6–12.7% → 4.7–6.0%（100 s）,观测间不升高（CDFS 2.1–2.8%）,代价 20–26% 活时间；H（2.5–8 keV）与 S（减半薄化）一致。未在新场或谱上验证。It holds on consumed CDFS and M31 (T023, exploratory): within 11.6–12.7% → 4.7–6.0% (100 s), the between term does not rise (CDFS 2.1–2.8%), at a 20–26% live-time cost; H (2.5–8 keV) and S (thinned halves) agree. Not validated on a fresh field or on spectra.	已冻结（D012）：H,B = 300 s,n = 1,在 2.filter 之内（commit abc5e602;打分 cell 1000 s）。下一步：一次 Lockman Hole 还原同时检验它与 P002 F2；谱上由 C2 检验。Frozen (D012): H, B = 300 s, n = 1, inside 2.filter (commit abc5e602; scoring at 1000 s cells). Next: one Lockman Hole reduction tests it together with P002 F2; C2 tests it on spectra.	T023 / 已消费数据上支持，未验证Supported on consumed data; not validatedT023 / Supported on consumed data; not validated
100 s cell 上约 5% 的快速"白"残差从哪来？Where does the ~5% fast "white" residual at 100 s cells come from?	它决定 C001 打分 cell 尺寸的选择：100 s 上它把观测内项顶在 ~5%,≥ 1000 s 时只剩 0–2.6%；它不跟随角落，且会从任何谱中平均掉。已定（D012）：主打分用 1000 s cell，100 s 与 3000 s 作诊断。It decides the choice of C001 scoring cell size: at 100 s it floors the within term at ~5%, at ≥ 1000 s only 0–2.6% remains; it does not follow the corner and averages out of any spectrum. Decided (D012): the primary score uses 1000 s cells, with 100 s and 3000 s as diagnostics.	两个未测的解释（E005/E006）:仪器事件聚簇（超泊松计数，100 s 处 Fano 因子 1.11–1.19,2.5 s 处 ≈ 1.03 —— 相关时间几十秒以上;非闪烁像素）,或裁剪阈值以下的快速软质子闪烁。检验方法：对只有粒子能到达的未曝光角落 0.5–2 keV 事件算同一统计量。Two untested explanations (E005/E006): instrumental event clustering (super-Poisson counting, Fano factor 1.11–1.19 at 100 s, ≈ 1.03 at 2.5 s — a correlation time of tens of seconds; not flickering pixels), or fast soft-proton flicker below the clip threshold. A test: the same statistic on unexposed-corner 0.5–2 keV events, which only particles reach.	建议（未经评审）：角落 0.5–2 keV 残差统计；结果并入 cell 尺寸或残差起源的后续决定（cell 尺寸本身已由 D012 定为 1000 s）。Suggestion (not reviewed): the corner 0.5–2 keV residual statistic; feed the result into the later decisions on the residual's origin (the cell size itself is already set to 1000 s by D012).

反事实 Al 亏损（−0.028 ± 0.013, MOS2）是真信号吗？Is the counterfactual Al deficit (−0.028 ± 0.013, MOS2) real?	若真，则 L_K = L_B 这个设计级约束本身有偏差；若假，则是未建模系统误差。它决定线门是否可信。If real, the design-level constraint L_K = L_B is itself biased; if not, it is an unmodelled systematic. It decides whether the line gate is trustworthy.	P002 F3 已处置（E004）：在 CDFS MOS2 上，线在观测之间跟随 Q(b = 1.015 ± 0.030）而观测之内的 K/B 线比不跟随角落 —— 指向线测量里的 K/B 系统误差。这成为 T005 在 MOS2 上的主要处置；P001 线门（L_K = L_B）作为粒子锚仍未被验证。Disposed by P002 F3 (E004): on CDFS MOS2 the line follows Q between observations (b = 1.015 ± 0.030) while the within-observation K/B line ratio does not follow the corner — pointing to a K/B systematic in the line measurement. This is the leading T005 disposition for MOS2; the P001 line gate (L_K = L_B) stays unvalidated as a particle anchor.	P002 F2（Lockman Hole）与"K/B 线系统误差"的专门预注册；在此之前不关闭。P002 F2 (the Lockman Hole) and a dedicated pre-registration on the K/B line systematic; not closed before that.

角落能否预测 K/B 粒子级变化？Can the corner predict the K/B particle-level change?	角落在 FOV 外、不经望远镜聚焦，是最干净的粒子监测器；若够准，就能直接检验"Al 亏损 = 粒子变化"。The corner is outside the FOV and receives no focused soft protons — the cleanest particle monitor; if precise enough it can test "Al deficit = particle change" directly.	已回答（按数据集，D006）：CDFS 上够准（σ = 0.0044 / 0.0038）且看到了真实的 K/B 粒子级差（被删时间高 1.9% / 3.9%）;M31 MOS1 上太吵（σ = 0.0133）。所以 2.filter 也删掉了粒子背景升高的时段，不只是软质子时段。Answered (per set, D006): precise enough on CDFS (σ = 0.0044 / 0.0038) and it sees a real K/B particle-level difference (rejected time 1.9% / 3.9% higher); too noisy on M31 MOS1 (σ = 0.0133). So 2.filter also cuts periods of elevated particle background, not only soft-proton time.	已由 CDFS E5 完成。遗留的子问题（未预注册）：Al 线不跟随角落 —— 见上面新行。Done by the CDFS E5. Remaining sub-question (not pre-registered): the Al line does not follow the corner — see the new row above.	T017 / 已按数据集回答ANSWERED per setT017 / ANSWERED per set
被移除的成分是软质子还是可变天体源？Is the removed component soft protons or variable celestial sources?	这是"删掉的东西到底是什么"的身份问题；M31 盘里有很多可变 X 射线双星，是天体源解释的真实竞争者。This is the identity question — what was actually removed; the M31 disk holds many variable X-ray binaries, a genuine celestial competitor.	A1:移除的超额 ~79% 无线 (Al −5.96σ);B1:空间延展、非紧凑，更像软质子花样；但仍不能排除多个微弱可变源。A1: the removed excess is ~79% line-free (Al −5.96σ); B1: extended, not compact — closer to the soft-proton pattern; many faint variable sources are not excluded.	CDFS E6（描述性）：CDFS 的中位增益（+0.0035 / +0.0029）比 M31（+0.0005 / +0.0011）大 3–10 倍，但同样远低于阈值 —— 与"移除成分主要是软质子、M31 的可变源压低了增益"相容，不构成证明。The CDFS E6 (descriptive): the median CDFS gain (+0.0035 / +0.0029) is 3–10× M31's (+0.0005 / +0.0011) but still far below threshold — compatible with "the removed component is mostly soft protons, with M31's variable sources diluting the gain", not proof of it.

(c) C2 谱验证（P002 之后，PI 决定是否等 F2）:把 C1 里最好的 2–3 个政策与 2.filter 用到 MosaicSelfCal CDFS 金/银 cell 上，按 LHB 与 halo 归一化的一致性 τ 打分，再上 M31CGM。成功标准：快速判据的排名与谱 τ 的排名一致。(c) C2 spectral validation (after P002; the PI decides whether it waits for F2): apply the 2–3 best C1 policies and 2.filter to the MosaicSelfCal CDFS golden/silver cells, score the consistency τ of the LHB and halo normalisations as the MosaicSelfCal spectral score does, then M31CGM. Success: the quick-metric ranking matches the spectral-τ ranking.

光变曲线 + 阈值滑块 → GTI、f_T、保留计数实时更新Light curve + threshold slider → GTI, f_T and retained counts update live

拖动阈值：蓝色是保留的时间 K,红色是被删的 B。f_T 是保留活时间比例；R 用玩具模型模拟"删高率时间为什么会让 R>1"。

Drag the threshold: blue is kept time K, red is rejected B. f_T is the retained live-time fraction; R uses a toy model to show why cutting high-rate time gives R > 1.

本次更新What's new

2026-10-14（第三次更新，D007–D012 刷新）:

2026-10-14 (third edition, the D007-D012 refresh):

PI 把下游成功判据定义为误差预算(C001,D007/D008):单观测看 σ_tot,多观测先看一致性；0.5–2 keV 拼接光变曲线的 s_sys = 17–25%（2.filter），对 s_stat 0.04–0.2% —— 系统误差约大 100 倍。The PI defined the downstream success criterion as the error budget (C001, D007/D008): σ_tot for a single observation, consistency first over a set; the 0.5–2 keV concatenated-light-curve s_sys is 17–25% (2.filter) against s_stat 0.04–0.2% — the systematic is about 100× larger.
历史的 M31 2.1.filter 在多个观测上灾难性失败（3 个 MOS2、5 个 MOS1 完全不切;另一些只留 0.1–2.9 ks），且其"1.6%"被撤回：它在 0.2–10 keV 上选择，包含 0.5–2 keV 打分带 —— 选择与打分同一批事件给出 0.0%。The historical M31 2.1.filter fails catastrophically on several observations (no cut at all on 3 MOS2 and 5 MOS1; 0.1–2.9 ks left on others), and its "1.6%" is withdrawn: it selects on 0.2–10 keV, which contains the 0.5–2 keV score band — selecting and scoring on the same events gives 0.0%.
C1（D010）：每个观测一个角落项把观测间部分从 ~12% 降到 3–4%（CDFS）;剩下的主导项是 2.filter 留下的 ~12% 观测内变化。C1 (D010): a per-observation corner term takes the between part from ~12% to 3–4% (CDFS); the dominant remainder is the ~12% within-observation variability left by 2.filter.
C1b（D011）：2.filter 内的不相交能段（FOV 2.5–8 keV）裁剪（B = 300 s,n = 1）把观测内项从 11.6–12.7% 减到 4.7–6.0%（100 s），代价 20–26% 活时间；≥ 1000 s 时 0–2.6%，达到 ~2% 目标。CDFS 角落修正后 s_sys:12.5% → 6.1%（MOS2）、12.0% → 5.2%（MOS1）。C1b (D011): a disjoint-band (FOV 2.5–8 keV) clip inside 2.filter (B = 300 s, n = 1) cuts the within term from 11.6–12.7% to 4.7–6.0% (100 s) for 20–26% of live time; at ≥ 1000 s it is 0–2.6%, meeting the ~2% target. CDFS corner-corrected s_sys: 12.5% → 6.1% (MOS2), 12.0% → 5.2% (MOS1).
P002 批准、冻结（1eb687b）并跑完 F1（D009）：CDFS MOS2 b = 1.015 ± 0.030 → TRACKS;其余三集 b ≈ 0.6–0.7 → INTERMEDIATE。"Al 线是粒子监测器"未在一般意义上确立。F3 指向线测量里的 K/B 系统误差（T005）。P002 was approved, frozen (1eb687b) and F1 run (D009): CDFS MOS2 b = 1.015 ± 0.030 → TRACKS; the other three sets give b ≈ 0.6–0.7 → INTERMEDIATE. "The Al line is a particle monitor" is not established in general. F3 points to a K/B systematic in the line measurement (T005).
100 s cell 上约 5% 的快速"白"残差是新的未解问题：裁剪后仍在、不跟随角落（观测内角落回归只移走 ≤ 0.7 点）、会从谱中平均掉；其来源未测（事件聚簇 Fano ≈ 1.17,或阈值下的快速软质子闪烁）。The ~5% fast "white" residual at 100 s cells is a new open question: it survives the clip, does not follow the corner (a within-observation corner regression removes ≤ 0.7 points), and averages out of spectra; its origin is untested (event clustering, Fano ≈ 1.17, or fast soft-proton flicker below the clip).
下一步（PI,D011/D012）:冻结已完成（H,B = 300 s,n = 1;cell 尺寸 1000 s;commit abc5e602），下一次是一次 Lockman Hole 还原，同时检验 P002 F2 与冻结滤波器；C2 在 P002 之后。Lockman Hole"后面再派"，不预设日期。Next (PI, D011/D012): the freeze is done (H, B = 300 s, n = 1; cell size 1000 s; commit abc5e602); the next step is one Lockman Hole reduction testing both P002 F2 and the frozen filter; C2 after P002. The Lockman Hole is dispatched later; no date invented.
新页面："误差预算与 Al 线"(budget.html),从零讲 C001 与 P002,含撤回的 1.6% 一节；两张新图:P002 F1 四集散点、C1b cell 尺寸依赖。New page: "Error budget and the Al line" (budget.html), teaching C001 and P002 from zero, including the withdrawn 1.6% claim; two new figures: the P002 F1 four-set scatter and the C1b cell-size dependence.

2026-10-13（第二次更新，D006 刷新）:P001 关闭，主问题否定;CDFS 盲测完成（E003）;角落按数据集回答;探索性角落–Al 张力（后由 P002 接手）。

2026-10-13 (second edition, the D006 refresh): P001 closed negative; the CDFS blind run complete (E003); the corner answered per set; the exploratory corner-vs-Al tension (later taken over by P002).

2026-10-13(第一版）:本手册随 ParetoGTICal 迁移入 DXC 后建立，覆盖 D001–D005。

2026-10-13 (first edition): this handbook was built after ParetoGTICal migrated into DXC, covering D001–D005.
