IS FPT distributions to β_A focused analysis (see main text). The red, light blue, blue, and gray lines represent the full FPT, focused FPT with Z < 0.2, Z < 0.3, and Z > 0.67, respectively (see text). Dashed lines show different functional fits. The two exponential fits have a characteristic time of 0.6 ps (dashed blue line) and 165 ps (dashed gray line). The fits have been slightly displaced for clarity. The fitting function for the full FPT distribution is f(t) = c₀t^-αe^-t/t₀ + c₁e^-t/t₁ + c₂e^-t/t₂, where c₀, c₁, c₂, α, t₀, t₁, and t₂ have a value of 704; 4,035; 88; 0.6; 33; 0.6; and 180, respectively.
