Notes. Parameters a, b, and c are the FP coefficients defined in Eq. (2). Δ is the root mean square of the residuals, Res ≡ (a + b log σe + c logΣe)−log Rhsm. The uncertainties on a, b, c, Δ, and Δ/Δr were computed by dividing the full sample into ten sub-samples and evaluating the standard deviation across these realizations.
