The selectivity of the products for the surface conditions shown in Figure~\ref{fig:ca_all} under an applied voltage of 650 V. 
    Conditions: 500 sccm He, 10 sccm O$_2$, 0.5 sccm C$_4$H$_{10}$. The products are arranged from left to right as CO (blue), CO$_2$ (green), CH$_4$ (red), and C$_2$H$_2$ (purple), unassigned species (gray). The unassigned species may originate from water or carbonaceous species on the dielectric and cannot be specifically identified.
