Equivalent-Width Abundance Proxy

ID: stellar.spectroscopy.abundance_proxy_equivalent_width

Represents line-strength or equivalent-width ratios as a diagnostic abundance proxy that still requires atmospheric modeling for serious abundance claims.

Status: diagnostic

Uncertainty

• This diagnostic badge is a theory locator; its claim still needs independent, claim-specific validation.
