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

Done. The file was already a single merged workbook (`Book1`, 15 powers, 5–100 µW), so I despiked (130 cosmic-ray spikes removed) and ran a **Lorentzian** fit on every spectrum (window 1.23–1.45 eV). All 15 peaks converged at **HIGH** quality (R² = 0.887–0.984).

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

| Power (µW) | Intensity (arb.) | xc (eV) | FWHM (meV) |
|---:|---:|---:|---:|
| 5 | 98.8 | 1.3206 | 62.4 |
| 10 | 189.9 | 1.3244 | 64.4 |
| 15 | 267.9 | 1.3264 | 64.1 |

**Allometric fit — intensity vs power (left panel):** $I = a\,P^{b}$
- $a = 16.28 \pm 1.81$
- $b = 1.0048 \pm 0.0261$
- R² = 0.995 → essentially linear (exponentic regime, no saturation up to 100 µW)

**Peak-position trend (right panel):** monotonic **blueshift** from 1.3206 → 1.3356 eV (~15 meV total), ≈ 5 meV per decade of power — the fitted curve tracks the exciton energy hardening with excitation power.
