Rotation Field of the Cosmic Microwave Background — Phenomenology & Physical Interpretation (v1.6)

Summary This dataset contains the rotation field α(n̂) of the CMB, derived from Planck 2018 polarization data. α(n̂) represents the rotation of the CMB’s linear polarization angle across the sky — a direct observable of cosmic birefringence. Across all versions of this archive (v1.0–v1.6), the same underlying α-map is used:• No recomputation from Q/U maps• No recalibration• No new null simulations The α(n̂) field is reconstructed using EB-only estimators (Minami & Komatsu 2020; MASTER calibration). DATA DISCIPLINE (applies to all versions)• α-map and mask are locked (SHA-256 tracked)• All outputs are written into new timestamped folders (never overwritten)• JSON + CSV parameter files enable full reproducibility• Notebooks and manifests included in each archive WHAT’S NEW IN v1.6 (THIS RELEASE)v1.6 adds interpretation to the structure identified in v1.5.• Subtracts best-fit ℓ = 1,2 (dipole + traceless quadrupole) from α(n̂) on the masked sky• Residuals show no additional organized multipole structure beyond those components• Imports the harmonic periodicity Δℓ from v1.5 into a predictive α(ℓ) band (v1.6 does not re-fit)• Converts rotation amplitude into physical units (rad → deg → arcmin → arcsec) No recalibration. No new null simulations. No new α-map. Deliverables archive includes:• Residual α(n̂) map after ℓ=1,2 subtraction (FITS + PNG)• Predictive α(ℓ) band (JSON + PNG)• Rotation amplitude table (JSON + CSV)• Manifest + README (all SHA-256 tracked) This release is part of an iterative research series in which analysis methods, masks, and calibration procedures were progressively refined. Later releases establish the physical calibration of the α(n̂) field.
