Corrigendum to "Ultra-high precision 40Ar/39Ar ages for Fish Canyon Tuff and Alder Creek Rhyolite sanidine: New dating standards required? (vol 121, pg 229, 2013)"

Abstract

The authors regret that typographical and calculation errors occurred in Table 1, Table DR1 and Appendix A in the manuscript. Most relate to inconsistent propagation of uncertainty levels (i.e. 2σ vs 1σ uncertainties) associated with the J-values reported for FCTs and ACRs aliquots in Table DR1 and typographical errors in the J-values reported for aliquots FC3/AC3 and FC4/AC4. Corrected versions of Table 1, Figs. 3 and 4, and Appendix A are shown below. These errors do not affect the conclusions of the original paper and we summarise the resulting changes to the abstract, Sections 4.2 and 5, and Appendix A below. Correct J-values for aliquots FC3/AC3 and FC4/AC4 in Table DR1 are 0.0025205 ± ..
