![Power Fit]([file link removed])

Lorentzian fits converged on all 15 power levels (R² = 0.887–0.984, all HIGH tier). Despiked first (130 cosmic-ray spikes removed).

**Intensity vs power — allometric fit I = a·P^b:**
- **b = 1.0048 ± 0.0261**, a = 16.28 ± 1.81, R² = 0.995
- Interpretation: ~linear (excitonic) — intensity scales proportionally with excitation power.

**Peak position (xc) vs power:**
- xc shifts from **1.3206 eV** (5 µW) → **1.3356 eV** (100 µW): a monotonic **blueshift** of ≈ 5 meV/decade, saturating toward high power.
- FWHM narrows from 62 meV → 54 meV over the same range.

RESULT: b = 1.0048 ± 0.0261
