Temperature rise $\Delta T$ (K) against squared rf voltage $V_{\mathrm{rf}}^2$ (kV$^2$) for parts 1 to 5 as labelled: measured points (circles) with error bars and fits of the form $k_{2}V_{\mathrm{rf}}^2 + k_{4}V_{\mathrm{rf}}^4$ (lines), and the simulated temperature rise seen by the ion (crosses, dashed). The dash-dotted line marks (350 V)$^2$.
This panel was computed from the authors' public data deposit (Zenodo: https://doi.org/10.5281/zenodo.17070662, CC BY 4.0), with the fit curves and the points at the origin recovered from the published vector figure. The plot shown here is re-rendered for interactive viewing and analysis. See the paper for the original figure and full scientific context.
