Recombination probability of hydroxyl radicals as function of binding energy of OH radical. The binding energy of the more weakly bound radical is shown on the x-axis. The first top left plot presents the results for all the energies combined. The following graphs present the datasets for different amounts of added energy individually, with the error bars included in the plots. Error bars represent Jeffreys Bayesian interval generated by Python library statsmodels (Seabold & Perktold 2010).
