The authors wish to make the following corrections to this paper  in Section 2.2, Equation (19). The authors wish to replace:
Alternatively, the following equation is an empirical fit for that is valid for and with a mean error of 1.7% and a maximum error of 5.9%:
While Equation (19) is only valid for aspect ratios not exceeding 50, the value of from Equations (16)–(18) in the limit for infinite aspect ratio () is zero.
Alternatively, the following equation is an empirical fit for that is valid for any aspect ratio and , with a mean error of 1.9% and a maximum error of 7.9% for :
In the limit for infinite aspect ratio (), the low-frequency approximation of obtained from Equations (16)–(19) is zero.
The authors would like to apologize for any inconvenience caused to the readers by these changes.
