Dark Energy Survey 5-year photometric SN Ia Hubble diagram (DES-Dovekie_HD.csv) with the stat+sys covariance in NumPy .npz form. Serves as the second, independent SN sample in the sample-swap robustness test: the evolving-DE preference rises from 2.4 sigma (Pantheon+) to 2.8 sigma with DES-SN5YR.

notes: The 'Dovekie' tag on the Hubble diagram indicates a post-2024 recalibrated version of the DES-SN5YR release; the arXiv citation is grounded in the engine's inline DES_SN5YR_BINNED table reference.

Serving, honestly

A download link here issues a short-lived redirect to our object-storage mirror (Tigris); the bytes come from there, not from this server, and the link expires after an hour. The upstream archive is always the canonical copy — cite it, not us. Anything we serve must match its published hash.
