Classification of Layer 5 of Cotopaxi volcano using the schemes of aPyle (1989) and bBonadonna and Costa (2013). When using Pyle (1989), one point is plotted for each isopach segment. For Layer 5, the blue and red dots are the proximal and distal segments, respectively. When using Bonadonna and Costa (2013), TephraFits plots a ±30% uncertainty on λ_TH and a ±50% uncertainty on λ_ML/λ_TH
