Regrettably, there was a mistake in Equation 4 of the original article.

The correct form of Equation 4 is

$$ {{{\delta }}^{{66}}}{\hbox{Z}}{{\hbox{n}}_{{{\rm{sample(true)}}}}} = {{{\delta }}^{{66}}}{\hbox{Z}}{{\hbox{n}}_{{{\rm{sample(measured)}}}}} - {{{\delta }}^{{66}}}{\hbox{Z}}{{\hbox{n}}_{{{\rm{London(measured)}}}}} $$
