Evidence atom

back to sources

Metallicity is the dominant source of systematic uncertainty in TRGB distance ladder: a ±0.2 dex error in mean [Fe/H] propagates to ±0.15–0.20 mag distance modulus error (~±7–10% in distance), nearly matching the current Hubble tension magnitude.

An evidence atom is an inspectable support unit. It is not a finding by itself; it supports or challenges a finding through review.
