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 detail for the first time the precise calibration and analysis methodology adopted in previous EDGES data releases and present these methods inside a new open-source end-to-end analysis and simulation package.

C2weakest assumption

That the methods now described in the paper are exactly the same procedures that were applied to produce the earlier EDGES data releases and that the validation tests shown are sufficient to resolve concerns about foreground subtraction and instrumental systematics.

C3one line summary

The EDGES team publishes the first full public description of its 21-cm global-signal analysis pipeline, an open-source end-to-end software package, and the raw data from prior observations.
