IV. Data, Processing & Results Summary

Coverage

Preprocessing pipeline

  1. Coordinate/mask harmonization, dipole–quadrupole decomposition with a common lock-in window.
  2. PV/kSZ joint inversion to estimate |V_bulk| and (l,b), then compute Δθ_⊥.
  3. Radio dipole demixing with multi-band templates to obtain D_radio and Q_radio.
  4. CMB dipole residuals: remove kinematic dipole and barycentric corrections → D_CMB^res.
  5. Weak-lensing cross: estimate C_{ℓ}^{vγ} and its covariance.
  6. Uncertainty propagation: total_least_squares + errors-in-variables for gain/mask/drift.
  7. Hierarchical Bayes (MCMC): stratified by radius/platform; Gelman–Rubin and IAT diagnostics; k = 5 cross-validation.

VI. Overall Assessment

Strengths

  1. Unified multiplicative structure (S01–S05) jointly captures |V_bulk| / Δθ_⊥ / A_kSZ / Q_radio / D_CMB^res / C_{ℓ}^{vγ}, with physically interpretable parameters—actionable for joint PV/kSZ/radio/lensing survey design.
  2. Mechanistic identifiability: significant posteriors for γ_Path / k_SC / k_STG / k_TBN / β_TPR / θ_Coh / η_Damp / ξ_RL and ψ_flow / ψ_density / ψ_shear / ζ_topo, separating flow response, density drive, and shear coupling.
  3. Operational utility: on-line calibration with J_Path / G_env / σ_env and mask/weight optimization stabilizes misalignment estimates and reduces system drifts.

Limitations

  1. Very large scales (R > 300 Mpc/h) remain sample-sparse with stronger foreground blending; fractional-memory kernels and nonlinear flow–lensing couplings may be required.
  2. Radio-dipole systematics (mask/gain/spectral index) can blend with Q_radio, demanding stricter multi-band self-calibration.

Falsification Line & Observational Suggestions

  1. Falsification. See the falsification_line in the front matter.
  2. Recommendations:
    • Radius-stratified maps: chart |V_bulk| and Δθ_⊥ over (R × mask) and test linear co-variance with A_kSZ, Q_radio.
    • kSZ depth field: extend cluster/group samples to z ≈ 0.6 to sharpen the posterior of A_kSZ.
    • Shear–flow joint fit: fit C_{ℓ}^{vγ} together with RSD/PV to constrain ψ_shear vs k_STG degeneracies.
    • Systematic control: lower σ_env and harmonize multi-band masks; quantify TBN → D_CMB^res, Δθ_⊥ linear impacts.
