I merged the spectra at each power and fitted the two resolved bands with a Lorentzian plus a linear background. The upper-edge rise is truncated, so it has no measurable peak position.

The allometric exponents \(b\) (with 1σ regression uncertainties) are:

- Peak intensity: 1.33 eV band, \(b=0.9126\pm0.0140\); 1.54 eV band, \(b=0.8535\pm0.0668\).
- Peak position: 1.33 eV band, \(b=0.004573\pm0.000101\); 1.54 eV band, \(b=0.001809\pm0.000562\).

The peak-by-power fit parameters are in [lorentzian_peak_results.csv](<BENCH>/raw/commercial/luna-high/bench/t-pl/run-24/lorentzian_peak_results.csv). The allometric plots are [peak intensity vs power](<BENCH>/raw/commercial/luna-high/bench/t-pl/run-24/peak_intensity_vs_power.png) and [peak position vs power](<BENCH>/raw/commercial/luna-high/bench/t-pl/run-24/peak_position_vs_power.png).

The requested final \(b\) is for the main, 1.33 eV peak intensity.

RESULT: b = 0.9126 ± 0.0140
