The CSV contains one merged spectrum for each of 15 powers. I fitted the two resolved peaks with a Lorentzian plus a local linear baseline. The fitted intensity is the Lorentzian height; the allometric fits use \(y=aP^b\). The uncertainties below are standard errors from the log–log regressions.

| Peak | Intensity exponent \(b\) | Position \(x_c\) exponent \(b\) |
|---|---:|---:|
| Near 1.33 eV | 0.915 ± 0.019 | 0.00454 ± 0.00015 |
| Near 1.54 eV | 0.898 ± 0.038 | 0.00192 ± 0.00036 |
