摘要：Maria Petropoulou and Bing Theodore Zhang brought to our
attention that in the original paper (Britzen et al. 2019), the righthand side of Eq. (14) had not been divided numerically by
c = 3 × 1010 cm s−1. This arithmetical error was carried through
to the subsequent equations as well. Furthermore, the scaling
factor, δ− I;14, from Eq. (13) was not carried through. Equation (14).
