Notes. Simulation results for a range of values of the parameter α for the internal twist model, where the current is confined to the region (V) inside the star. The first column is α, subsequent columns are Ψ₀^norm, the magnetic flux of the first closed field-line, L_twisted/L_untwisted the ratio of the spin-down luminosity of a magnetosphere with twist in the closed field-line region L_twisted to a standard pulsar solution with twist only in the open field-lines L_untwisted, ${\mathrm{\Psi }}_{\max }^{\mathrm{norm}}$ and ${\mathrm{\Psi }}_{\mathrm{ssf}}^{\mathrm{norm}}$ as shown in Table 1 We note that Δϕ = 0 and R_T = 1; thus, they are not shown here.
