Compressed CMB likelihood summaries — shift parameter R, acoustic scale l_a, omega_b, z_star, n_s — for Planck 2018, ACT DR6 and SPT-3G, stored as the CMB_PRIORS inline Python dict. This is the 'Planck CMB (compressed)' ingredient in every expansion-seam fit.

notes: inline table; download = extract from source file. HONESTY WARNING: catalogs.py source is currently 0 bytes (truncated 2026-02-18); the tables survive only in the compiled bytecode __pycache__/catalogs.cpython-312.pyc (verified 2026-07 by loading that module directly). Reconstructing catalogs.py from the bytecode is an open task.

Serving, honestly

Downloads are served directly from this server today; an object-storage mirror (Tigris) is planned and flips on via config. The upstream archive is always the canonical copy — cite it, not us. Anything we serve must match its published hash.
