IV. 数据、处理与结果摘要

数据来源与覆盖

预处理流程

  1. 坐标/掩膜统一;偶极—四极分解与锁相窗一致化。
  2. PV/kSZ 联合反演:求解 |V_bulk| 与方向 (l,b),并计算 Δθ_⊥。
  3. 电台源偶极:多频模板回归得 D_radio 与 Q_radio。
  4. CMB 偶极残差:扣除动生偶极与日地速度修正得 D_CMB^res。
  5. 弱透镜交叉:估计 C_{ℓ}^{vγ} 及误差协方差。
  6. 误差传递total_least_squares + errors-in-variables 覆盖增益/掩膜/漂移。
  7. 层次贝叶斯(MCMC):按半径/平台分层,Gelman–RubinIAT 判收敛;k=5 交叉验证。

VI. 总结性评价

优势

  1. 统一乘性结构(S01–S05) 同时刻画 |V_bulk|/Δθ_⊥/A_kSZ/Q_radio/D_CMB^res/C_{ℓ}^{vγ} 的协同演化,参量具明确物理含义,可指导 PV/kSZ/电台源/透镜 的联合观测设计。
  2. 机理可辨识: γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL 与 ψ_flow/ψ_density/ψ_shear/ζ_topo 后验显著,区分流响应、密度驱动与剪切耦合贡献。
  3. 工程可用性: 通过 J_Path/G_env/σ_env 在线标定与掩膜/权重策略优化,可稳定错位角估计并降低系统漂移。

盲区

  1. 极大尺度(R>300 Mpc/h) 的样本稀疏与前景串扰增加,需引入分数阶记忆核非线性流—透镜耦合项。
  2. 电台源偶极系统学(掩膜/增益/谱指数)可能与 Q_radio 混叠,需更严格的多频自洽校准。

证伪线与观测建议

  1. 证伪线: 见前述 falsification_line
  2. 观测建议:
    • 半径分层相图: 在 (R × 掩膜) 平面标注 |V_bulk|、Δθ_⊥,检测与 A_kSZ、Q_radio 的线性协变。
    • kSZ 深度场:扩大群团样本至 z≈0.6,细化对 A_kSZ 的后验分辨率。
    • 剪切—流联合:C_{ℓ}^{vγ} 与 RSD/PV 同步拟合,约束 ψ_sheark_STG 的退化。
    • 系统学抑制:加强 σ_env 控制与多频掩膜一致化,量化 TBN → D_CMB^res、Δθ_⊥ 的线性贡献。
