The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

With the 10.3-year subset, we report evidence for a GWB, with a Bayes factor of 60 and a false alarm probability of about 0.1% (≳3σ significance).

C2weakest assumption

That the common red-noise process detected across pulsars is produced by gravitational waves rather than unmodeled instrumental or interstellar effects, given the reported mild tension between the full dataset and the modern subset spectra.

C3one line summary

EPTA second data release reports Bayes factor of 60 for an isotropic nanohertz GWB in the 10.3-year subset, with amplitude (2.5±0.7)×10^{-15} at 1 yr^{-1} when spectral index is fixed at 13/3.
