✓ Portable graph bundle live · download bundle · merged state

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

Commonly used analytic approximations for the continuum emission are systematically about 10 to 15% lower than our numerical solutions.

C2weakest assumption

The isothermal, constant-density plane-parallel slab geometry adequately represents the emission and polarization properties of real protoplanetary disks at millimeter wavelengths.

C3one line summary

Common analytic approximations underestimate protoplanetary disk millimeter continuum emission by 10-15%, causing overestimates of optical depth, mass, and temperature in SED analyses.
