Merged the spectra by power and fit the dominant band near 1.33 eV with a Lorentzian plus linear baseline. The fitted peak intensities and positions, with allometric fits, are in [lorentzian_peak_fits.csv](<BENCH>/raw/commercial/luna/bench/t-pl/run-17/lorentzian_peak_fits.csv). The two plots are in [lorentzian_allometric_fits.png](<BENCH>/raw/commercial/luna/bench/t-pl/run-17/lorentzian_allometric_fits.png).

For intensity versus power, the allometric exponent is \(b=0.9126\), with standard error \(0.0141\) from the log-log regression.

RESULT: b = 0.9126 ± 0.0141
