In [1], Eq. (2) had a typo and should read
(2)$$\sigma _{e -}^2 = \eta {\mu _{e
-}}\left[{\frac{{{e^{hc/\lambda kT}}}}{{{e^{hc/\lambda kT}} - 1}}}
\right].$$
Additionally Eq. (19) is of the form $${F_{{\hat{\textbf p}}}}(\hat p)
= \int_0^\infty {f_{{\hat{\textbf y}}}}(\hat y){F_{{\hat{\textbf
x}}}}(\hat p + \hat y) {\rm{d}}\hat y,$$
which holds for all $\hat p \in {\mathbb
R}$ since ${F_{{\hat{\textbf x}}}}(t) =
0$ for all $t \le 0$. However, when substituting an explicit form
for ${F_{{\hat{\textbf
x}}}}$ one must take this into account so that
Eq. (19) should read
(19)$${F_{{\hat{\textbf p}}}}(\hat p)
= \frac{{\beta _2^{{\alpha _2}}}}{{\Gamma ({\alpha _1})\Gamma ({\alpha
_2})}}\int_{\max \{0, - \hat p\}}^\infty {\hat y^{{\alpha _2} - 1}} {e^{-
{\beta _2}\hat y}} \gamma \!\left({{\alpha _1},{\beta _1}(\hat p + \hat
y)} \right) {\rm{d}}\hat y.$$
This
same error was also carried through to Eqs. (50) and (51), where the
maximizations need only be performed on the intervals $x \in [- \sigma _{\textbf{y}}^2,
\infty)$ and $x \in (- \infty , \sigma
_{\textbf{x}}^2]$, respectively.These errors do not affect any of the results or conclusions presented in the
paper.
