Corrigendum to “Assessing tephra total grain-size distribution: Insights from field data analysis” [Earth Planet. Sci. Lett. 443 (2016) 90–107] (S0012821X16300577)(10.1016/j.epsl.2016.02.040)

The authors found a mistake in the formulation of the distribution named Bi-Weibull distribution reported in the equation (A.2) of the Appendix A. The error affects equation (4) (which is the same as eq. (A.2)) and Table 4 in the original manuscript. In equation (A.2) the normalization constants were missing and there was an error in the argument of the exponent. The correct normalized distribution is:[formula fresented]. The corrected Table 4 and Fig. A.1 are reported below.
