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

**Lorentzian fit — all 15 powers (5–100 µW), window 1.23–1.45 eV.** Every column converged to the HIGH tier (R² = 0.887–0.984, median 0.981; SNR 7.6–24). Data were despiked first (130 cosmic-ray spikes removed).

**Per-power extracted values (Lorentzian):**

| Power (µW) | Intensity (counts) | xc (eV) | FWHM (meV) |
|---|---|---|---|
| 5 | 98.8 | 1.3206 | 62.4 |
| 20 | 353.8 | 1.3278 | 62.7 |
| 50 | 818.3 | 1.3328 | 59.0 |
| 100 | 1714.6 | 1.3356 | 54.4 |

**① Peak intensity vs power — allometric fit I = a·Pᵇ**
- **b = 1.0048 ± 0.0261**, a = 16.28 ± 1.81, R² = 0.995
- b ≈ 1 → **linear (excitonic)** regime; no saturation or bi-exciton quenching across 5–100 µW.

**② Peak position (xc) vs power**
- Monotonic **blueshift** from 1.3206 eV (5 µW) to 1.3356 eV (100 µW) — a total shift of **~15 meV**, trending toward saturation (slope ≈ 5 meV/decade). FWHM narrows from ~62 → ~54 meV with increasing power.

The allometric power-law exponent (from the intensity fit) is:

RESULT: b = 1.0048 ± 0.0261
