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

The volumetric heating rate in bright coronal loops is proportional to B². The synthesized EUV images reproduce many key coronal emission features seen in remote sensing observations of active region 11640.

C2weakest assumption

The hybrid coupling between long-term zero-β idealized models and shorter-period radiative MHD runs introduces no significant artifacts at the interface and that the observational magnetic-field boundaries faithfully represent the true photospheric evolution without unresolved small-scale flux.

C3one line summary

Data-driven MURaM simulations of emerging active region 11640 reproduce key EUV features and find volumetric coronal heating proportional to B squared along with ubiquitous MHD waves.
