I fitted each spectrum with two local Lorentzians plus a sloping baseline. Intensity is the fitted peak height above baseline; \(x_c\) is the fitted center. The second band was fit over 1.49–1.575 eV to avoid the rise at the CSV’s upper energy boundary.

Allometric fits use \(y=aP^b\), fit in log space. The dominant band’s intensity exponent is \(b=0.9013\pm0.0085\). For the second band it is \(0.893\pm0.070\). For peak position, the exponents are \(0.00454\pm0.00008\) and \(0.00202\pm0.00057\), respectively. Uncertainties are standard errors of the fitted exponents.
