The authors wish to make the following two corrections to this paper []:
(1). In the original article, there was a mistake in Figure 6 as published. Standard uncertainty of the arithmetic mean should be corrected. The original Figure 6 appears below.
The corrected Figure 6 appears below.
Figure 6.
Synthetic example of the standard uncertainty of the estimated temperature using arithmetic mean and the inverse-variance weighted mean.
(2). Final sentence of Section 10.1 should be changed from “The standard uncertainty of the inverse-variance weighted mean is shown with the solid black line and is much smaller along the entire fiber” to "The standard uncertainty of the inverse-variance weighted mean is shown with the solid black line and is much smaller near the ends of the fiber. The standard uncertainty of the inverse-variance weighted mean is equal to that of the arithmetic mean where the standard uncertainty of the forward-channel measurements is equal to that of the backward-channel measurements”.
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
