An error appears in Eqn 4 (p. 3521), which is propagated throughout the remainder of the manuscript. The correct version of the equation is as follows:
where the factor 1/CAM denotes the element-wise inverse of the added-mass tensor.
The conclusions of the manuscript are unaffected by the error; however, the quantitative interpretation of the wake vortex ratio (Wa) is revised accordingly.
The author apologises for any inconvenience this may cause the reader.
