Abstract

A misprint in our manuscript is reported and corrected.

There is a typo 0.041844 in Eq. (4) of our paper [1]. The value of 0.041844 should be corrected as 0.41844.

[\begin{array}{l} R \\ G \\ B \end{array}] = {[\begin{matrix} 2.7689 & 1.7517 & 1.1302 \\ 1.0000 & 4.5907 & 0.0601 \\ 0.00000 & 0.0565 & 5.5943 \end{matrix}]}^{- 1} [\begin{array}{l} X \\ Y \\ Z \end{array}] = [\begin{matrix} 0.41844 & - 0.15866 & - 0.08283 \\ - 0.09117 & 0.25242 & 0.01570 \\ 0.00092 & - 0.00255 & 0.17858 \end{matrix}] [\begin{array}{l} X \\ Y \\ Z \end{array}] .

The authors regret and apologize for the error, which does not affect any of the results or simulations presented in [1].
