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

After correction, the rms noise in the polar background is reduced by approximately 67% on average, and the signal-to-background ratio improves by a factor of up to 3.7 under heavy contamination conditions. The corrected radial intensity profiles restore the hydrostatic exponential decay corresponding to a plasma temperature of approximately 2.0 MK.

C2weakest assumption

That the polar coronal holes provide an independent, uniform constraint sufficient to uniquely determine the dust-scattering model parameters without introducing bias into the corrected streamer structures.

C3one line summary

A forward-modeling correction using real-time lens imaging reduces dust stray-light noise by 67% and restores expected coronal intensity profiles in ground-based data.
