For mass ratio ﹩{m}_{{\rm{i}}}/{m}_{{\rm{e}}}=1836﹩, magnetization ﹩{\sigma }_{w}=0.1﹩, and upstream temperature ratios ﹩{T}_{{\rm{e}}}/{T}_{{\rm{i}}}=0.1﹩ (blue), 0.3 (green), and 1 (red), we present the ﹩{\beta }_{{\rm{i}}}﹩ dependence of heating efficiencies: (a) electron total, ﹩{M}_{T{\rm{e}},\mathrm{tot}};﹩ (b) electron adiabatic, ﹩{M}_{T{\rm{e}},\mathrm{ad}};﹩ (c) electron irreversible, ﹩{M}_{T{\rm{e}},\mathrm{irr}};﹩ (d) proton total, ﹩{M}_{T{\rm{i}},\mathrm{tot}};﹩ (e) proton adiabatic, ﹩{M}_{T{\rm{i}},\mathrm{ad}};﹩ (f) proton irreversible, ﹩{M}_{T{\rm{i}},\mathrm{irr}};﹩ (g) electron and proton total, ﹩{M}_{T{\rm{e}},\mathrm{tot}}+{M}_{T{\rm{i}},\mathrm{tot}};﹩ (h) electron and proton adiabatic, ﹩{M}_{T{\rm{e}},\mathrm{ad}}+{M}_{T{\rm{i}},\mathrm{ad}};﹩ (i) electron and proton irreversible, ﹩{M}_{T{\rm{e}},\mathrm{irr}}+{M}_{T{\rm{i}},\mathrm{irr}}﹩.
