The mean relative \(L^\infty\)-norm error in the barycentric polynomial interpolation of TEPs, averaged over 276 TEPs. (top) Chebyshev nodes vs. equidistant nodes, (bottom) Chebyshev-node case only, with error bars. The error bars indicate the 95% CIs for population mean. The omitted CIs for equidistant nodes are given in the SI.
