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 successfully use reverberation mapping to constrain the masses of 62 super-massive black holes, and combine with existing data to fit a power law to the lag-luminosity relation for the Hβ and MgII lines with a scatter of ~0.25 dex, the tightest yet identified, fit specifically for consistency with high redshift AGN.

C2weakest assumption

That the reverberation mapping time lags measured in visible light for Hβ, MgII, and CIV accurately trace the broad-line region radius at redshifts up to 3.85 and that selection effects from finite survey length fully explain the CIV tension with low-luminosity samples.

C3one line summary

OzDES final release delivers 62 new reverberation-mapped black hole masses and tighter lag-luminosity relations for Hβ, MgII, and CIV in high-redshift AGN after correcting for survey-length selection effects.
