Reaction rate uncertainties for the ³⁵Ar(p, γ)³⁶K reaction assuming the resonance parameters shown in Table 2. Recall that only resonance energies are taken into account. The rate has been normalised to the median rate, which is shown by a dashed line at unity. The thick and thin black lines represent the 1σ and 2σ uncertainties in the correlated resonance energy calculation. The blue lines show the uncorrelated case, with the thick line representing the median rate (again, normalised to the recommended correlated energy rate), and dashed lines showing the 1σ uncertainties. At T = 400 MK, the effect of correlations slightly decreases the reaction rate uncertainty.
