The companion paper of Allen and Eckel (2012) was incorrectly referenced in the original paper. Eckel et al. (2012) was referenced with the year 2011 instead of 2012, and was incorrectly referred to as E11 instead of E12 throughout the text. This paper is correctly referenced in this corrigendum and should have appeared like this in the original paper.
