Text Correction

There was an error in the original publication [1]. Equation (1) was incorrectly typeset. The last term in the numerator of the error function (erf) should be σ²/τ.

A correction has been made to Section 2. Methods, Section 2.4. Optical Parameter Model, Equation (1). The correct equation is:

\begin{matrix} M I R F (t) = \frac{A_{1}}{\sqrt{2 π} σ} \cdot \exp (- \frac{{(t - t_{0})}^{2}}{2 σ^{2}}) + \\ \frac{A_{2}}{2 τ} \exp (\frac{1}{2} {(\frac{σ}{τ})}^{2} - (t - t_{0}) / τ) \cdot (1 + \erf (\frac{t - t_{0} - σ^{2} / τ}{\sqrt{2} σ})) + b \end{matrix}

(1)

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
