Data and code for "Predicting the Faraday Rotation of the Azimuthal Polarization Modes in Simulated Black Hole Images"

Pre-registration emails, scoring scripts (with SHA-256 hashes), per-pair result files, the patched ipole source and a README audit map for the nine pre-registered tests of the paper "Predicting the Faraday Rotation of the Azimuthal Polarization Modes in Simulated Black Hole Images" (N. Quatela). The tests check a parameter-free predictor of the Faraday rotation of the azimuthal polarization modes in simulated (GRMHD) black hole images, and a simulation-only validity condition for it. All images were made from the public v3 GRMHD library (Dhruv et al. 2025) with ipole. The README maps each test to its pre-registration email, script, data, results and paper section.
