I treated the consistent dominant peak near 1.33 eV as the peak of interest. For each power, I fit a Lorentzian with a linear baseline over 1.27–1.40 eV. The plotted allometric fits use \(y = aP^b\) and log–log least squares.

- Peak intensity exponent: \(b = 0.913 \pm 0.014\)
- Peak position exponent: \(b = 0.00457 \pm 0.00010\)

The plots are in [allometric_fits.png](<BENCH>/raw/commercial/luna/bench/t-pl/run-19/allometric_fits.png), and fitted peak intensities, positions, fit errors, and FWHM values for each power are in [lorentzian_peak_fits.csv](<BENCH>/raw/commercial/luna/bench/t-pl/run-19/lorentzian_peak_fits.csv).

RESULT: b = 0.913 ± 0.014
