Maximum reconnection rates and magnetic field strengths ﹩{B}_{x}﹩ for the runs in Group B. (a) Maximum reconnection rates normalized by upstream magnetic field and Alfvén speed. (b) Magnetic field strengths ﹩{B}_{x}﹩ are taken when reconnection rates reach the maxima. The boundaries of the inner EDR are presented by dashed lines, determined by the zero crossings of ﹩{\left({\boldsymbol{E}}{\boldsymbol{+}}{{\boldsymbol{V}}}_{e}\times {\boldsymbol{B}}\right)}_{y}﹩ along ﹩x=0﹩. (c) Maximum reconnection electric fields normalized by the magnetic field strength and electron Alfvén speed at the inner EDR boundary.
