Notes. Top rows are for inelastic cross-section parameters defined w.r.t. T99, while bottom rows are for production cross sections defined w.r.t. W03. For information purpose, the numbers in parenthesis correspond to the maximum estimated uncertainties the given reaction has on B/C (as read from Figs. E.1 and E.2). From left to right, the nuisance parameters correspond to a normalisation, energy scale, and a modification of the slope below an energy threshold . Unused parameters are indicated by “−”. Parameters with σ = 0 amount to fixed parameters.
