The question, scope, and sources behind this Registry record.
Record the 2022 CODATA recommended value of first radiation constant for spectral radiance in W m^2 sr^-1.
Current frontiers derived from accepted Claims.
A published value under the current specification, not two opposing bounds.
Assertions tied to evidence, attribution, and review.
The frontier as it changed over time.
Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
