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

We find S_8 ≡ σ_8 √(Ω_m / 0.3) = 0.891^{+0.057}_{-0.084}, consistent at the 0.79 σ level with Planck and between 0.87 to 1.51 σ with other weak lensing surveys.

C2weakest assumption

The prior on the intrinsic alignment amplitude A_IA drawn from direct measurements and the assumption that baryonic feedback modeling plus scale cuts do not introduce significant bias in the S8 posterior.

C3one line summary

UNIONS weak lensing data constrains S8 to 0.891^{+0.057}_{-0.084} in non-tomographic harmonic space, consistent with Planck at 0.79 sigma under LambdaCDM.
