I identified two peaks and fitted each spectrum with a Lorentzian plus a linear background. The full fitted intensity and peak position (\(x_c\)) for every power are in [lorentzian_fits.csv](<BENCH>/raw/commercial/luna/bench/t-pl/run-15/lorentzian_fits.csv). The plots show both peaks and their allometric fits: [allometric_fits.png](<BENCH>/raw/commercial/luna/bench/t-pl/run-15/allometric_fits.png).

For the stronger peak, the allometric fit to intensity versus power gives \(b=0.9233\pm0.0121\). The weaker peak’s intensity fit gives \(b=0.8664\pm0.0381\).

RESULT: b = 0.9233 ± 0.0121
