I identified two recurring spectral bands and fit each spectrum in each band with a Lorentzian plus a linear baseline. The fitted peak intensities and positions are in [lorentzian_peak_fits.csv](<BENCH>/raw/commercial/luna/bench/t-pl/run-28/lorentzian_peak_fits.csv).

The requested plots show both bands and their allometric fits: [peak intensity vs. power]( <BENCH>/raw/commercial/luna/bench/t-pl/run-28/peak_intensity_vs_power.png) and [peak position vs. power]( <BENCH>/raw/commercial/luna/bench/t-pl/run-28/peak_position_vs_power.png). For the primary band near 1.33 eV, the intensity fit is \(I=aP^b\), with \(b=0.9180\) and standard error \(0.0127\).

RESULT: b = 0.9180 ± 0.0127
