Cobaya CPL + full Planck 2018 MCMC chains

Name: Cobaya CPL + full Planck 2018 MCMC chains
Creator: This program (Cobaya + Planck 2018 likelihood)

derived This program (Cobaya + Planck 2018 likelihood) 11 files · 31.6 MB

Eight MCMC chains for the CPL (w0-wa) model against the FULL Planck 2018 likelihood (lowl TT+EE, highl TTTEEE-lite, lensing) — the proper nested-likelihood cross-check behind the honest-core dark-energy result, run with Cobaya. Converged to Gelman-Rubin R-1 = 0.019. GetDist-loadable; the run config (input/updated yaml, covmat) is included for exact reproduction.

NO UPSTREAM URL ON RECORD — nothing sourceable was found on disk, and we don't invent links. See notes.

notes: The gold-standard cross-check: while the registry's headline fit uses a fast compressed likelihood, THIS is the full-likelihood MCMC that confirms it. R-1=0.019.

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.
