In the original article, two typographical errors occurred in equations. Equation (5) was specified as:

$\begin{array}{l}\Delta {\theta }_{SM}=\frac{1-e^{(-0.15·PAR)}}{1+e^{(-3·I_g)}}\end{array}$

but the first term of the numerator should have contained a positive rather than a negative. The correct version is:

$\begin{array}{l}\Delta {\theta }_{SM}=\frac{1+e^{(-0.15·PAR)}}{1+e^{(-3·I_g)}}\end{array}$

There was also an error in Equation (7). The growth term of the model, derived from coefficients in Figure 2, was incorrectly expressed as:

$\begin{array}{l}\hfill u=[1.57+\left(\frac{1}{{\theta }_{DM}·-16.8}\right)·(0.0125+\left(\frac{1}{{\theta }_{PaM}·-47.03}\right)]\\ \hfill ·[1-e^{(-5·PAR(z))}]\end{array}$

but should have been written as:

$\begin{array}{l}\hfill u=[\left(\frac{1}{{\theta }_{DM}}(-16.80)+1.57\right)\\ \hfill ·\left(\frac{1}{{\theta }_{PaM}}(47.03)+0.0125\right)]·[1-e^{(-5·PAR(z))}]\end{array}$

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
