I inspected the file, but I ran out of tool budget before I could execute the actual fitting pipeline, so I **cannot** give you a real `b` value yet. Here is exactly where things stand.

**Confirmed from inspection:**
- Single workbook `Book1`, sheet `Sheet1`. Column A = energy axis in **eV** (range ≈ 1.196–1.606 eV).
- Columns 2–15 are the 15 power levels: **5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100 µW**. These are already the merged per‑power spectra (one column per power), so no multi‑folder merge is needed.
- Suggested fit window: **x_min = 1.23, x_max = 1.45 eV** (dominant peak).
- No separate Si/reference folder exists in this project (only `/`), so Si background subtraction is not applicable here.

**Not yet done (blocked by tool budget):**
- Despike (mandatory before any fit)
- Lorentzian batch fit across all 15 spectra (`profile="lorentz"`)
- Extraction of per‑power intensity and xc
- The two plots (intensity vs power; xc vs power)
- The allometric fits (y = a·P^b) on each

Because none of the fits were run, I have **no measured peak positions, intensities, or allometric exponent**. I will not invent a number for `b` — doing so would be fabrication.

To unblock this, please confirm: **may I re‑run the full pipeline (despike → Lorentzian batch fit over 1.23–1.45 eV → extract intensity & xc → plot both vs power → allometric fit), and which of the two allometric fits (intensity‑vs‑power or xc‑vs‑power) should the final `RESULT: b = …` line report?**
