In the original publication of the article, while aligning figures for pagination, Eq. (26) was hidden behind Fig. 7. The Eq. (26) should read as given below:

$$ \eta_{{G_{\omega } }} = \frac{{\int\limits_{W} {\frac{1}{{K_{{G_{\omega } }} }}{\text{d}}W} }}{{\int\limits_{W} {{\text{d}}W} }}\quad \eta_{{G_{\nu } }} = \frac{{\int\limits_{W} {\frac{1}{{K_{{G_{\nu } }} }}{\text{d}}W} }}{{\int\limits_{W} {{\text{d}}W} }} $$

(26)

The original article has now been corrected.
