Replication package for "On the uniform, achromatic rotation of CMB polarization"

This dataset is the replication package for the Letter “On the uniform, achromatic rotation of CMB polarization”. It contains the exact figure PDFs used in the manuscript and the minimal numerical artifacts needed to verify the reported numbers, with no external data dependencies. The archive includes the two figure PDFs sized for journal use (fig1_beta_comparison.pdf, fig2_slope_check.pdf), the parameter/convention file constants.yaml, the summary file data_beta_summary.csv, and an optional self‑contained script reproduce_prediction.py that recomputes the theoretical prediction without using any CMB data. Angles are in degrees and follow the manuscript’s sign convention β ≡ −β_exp; the optional ν^−2 slope uses units deg·GHz². Figures can be cited or reused directly; numerical values quoted in the paper can be checked against constants.yaml and data_beta_summary.csv. The script is provided for convenience and has no external dependencies. Licensing: code is MIT; figures and data are CC BY 4.0. For citation, please cite the DOI of this dataset together with the manuscript; if a version‑agnostic reference is preferred, cite the concept DOI.
