After publication of the original article , it came to the authors’ attention that there were errors affecting the equations and Table 3. These corrections were mentioned by the authors during the proofing process, but unfortunately not implemented before final publication.
Equations 9–11, 14, 18 and 20 were published containing minor typographical errors, affecting subscript characters, special characters and line breaks. These equations have been updated in the original article and, accordingly, references to these equations within the main text have been corrected also.
In Table 3, the distribution of the columns was incorrect. The ‘MAC-NPC’ and ‘MAC-NPC2’ column headings should each have been over two sets of “t * = 5 years” and “t * = 10 years” sub-headings. In turn, these sub-headings should have contained 6 columns; the ‘MAC-NPC2’ heading contained 7, an extra ‘rmstD’ column. This has been corrected in the original article.
In addition, the authors noticed an error in Figure 3 which was not submitted at proofing. The vertical dashed line should have crossed the black diamond, representing the overall rmstD, through the center. A correct version of Fig. 3 is now present in the original manuscript and is published in this erratum.
