(Colour online) Example of a single rate sample of the ²²Ne(α, γ)²⁶Mg reaction using the parametrised rate factor variations. Plotted in the lower panel is the reaction rate ratio (i.e., compared to the recommended rate). Therefore, the line at unity represents the recommended rate, while a point at 10 means that the rate is 10 times that of the recommended rate. The red density distribution represents the coverage probability of the reaction rate, with thick and thin black lines denoting the 68% and 95% uncertainties, respectively. The dashed blue line represents a single sample of the reaction rate obtained when using Eq. (3) with p(T) determined from the parametrisation in Eq. (4) and shown in the top panel.
