  This is an addendum to the article of Qi Zhong cited above [arXiv:0705.2000].
It outlines how to apply the main result of that article to calculate the
asymptotics of the expected energy of zeros of random polynomials on the
Riemann sphere $S^2$ with respect to the log chordal distance $\log [z, w]$.
The cited article did not calculate the asymptotic energy this way, but by an
ad-hoc method, and the calculation contained some errors. The correct
calculation here agrees (up to the stipulted remainder) with that of Armentano-
Beltran-Shub.
