HERA window comparison: notice hera-h1c-idr2-window-extract.json is a derived extract of the public HERA Phase I (H1C IDR2) power-spectrum files distributed by the HERA Collaboration as HERA_2021_pspec_data.zip at https://reionization.org/science/public-data-release-1/ (file URL https://reionization.org/manual_uploads/HERA_2021_pspec_data.zip). The paper (HERA Collaboration 2022, ApJ 925, 221; arXiv:2108.02263v1) states that the data behind its Tables 3 and 4 and Figures 17 and 18 are publicly available. The release page names no licence. This extract is redistributed for teaching and verification only; cite the HERA paper when you use it. model-spectra.json is an ideal reference produced by Sandbox Physics: a density-only linear prediction, not a fit to HERA data and not a HERA product. Real observation, model prediction and any synthetic Lab record are kept in separate files and carry their own labels.
