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 outcome is to emphasize the practical tradeoffs among reconstruction accuracy, numerical stability, and suitability for real-time or offline usage of these reconstruction methods, particularly for the IRVB camera viewing system.

C2weakest assumption

The synthetic phantoms and forward modelling process accurately represent the line-integrated signals and noise characteristics encountered in real IRVB measurements on plasma devices.

C3one line summary

Compares MFI, PTR, and MLEM tomographic methods for IRVB data reconstruction using synthetic phantoms of plasma emissivity profiles.
