Figure 2

The mean relative \(L^1\)-norm error arising from the barycentric polynomial interpolation of TEPs, averaged over 276 TEPs. The interpolated TEP curves are compared to the exact TEP curves. (top) Chebyshev nodes vs. equidistant nodes, (bottom) Chebyshev-node case only, with error bars. The error bars indicate the 95% confidence intervals (CIs) for population mean. The CIs for equidistant nodes are omitted here and given in the SI because they are too large to draw.
