The argument presented just after Equation (3.4) in this paper contains a consequential error that undermines the approach taken to the upper bound on the shape. The author acknowledged the error and provided a correct approach to the upper bound in [Reference Biggins2] and had used a correct argument earlier, in [Reference Biggins1]. Relevant results are also given in [Reference Biggins3, Section 4.2].
