I'm struggling to see how to submit a small typo to the IEEE. I did read that it should be possible to enter your comment at the bottom of the article on IEEE Xplore under "Comments". However, the
IEEE Xplore page I'm looking at doesn't have a comments section.
The typo is in the coefficients listed in Annex D, Equation D.55. The k5 coefficient should be equal to 4.556*10^-10 (i.e. the third decimal place is missing).
It's hardly worth reporting on its own, but could be added to the existing
Errata document.
