Overview of the solar wind reconnection event. (a)–(c) Three components of the magnetic field ﹩{B}_{L}﹩, ﹩{B}_{M}﹩, and ﹩{B}_{N}﹩. (d) The L component of the ion bulk velocity ﹩{V}_{{iL}}﹩ and (e) electron bulk velocity ﹩{V}_{{eL}}﹩, which have had the background velocity subtracted −200 km s−1; (f) the M component of electron bulk velocity ﹩{V}_{{eM}}﹩. We have removed the background velocity from these bulk velocities; (g) energy dissipation rate ﹩{{\boldsymbol{J}}}_{p}{\rm{\cdot }}({\boldsymbol{E}}+{{\boldsymbol{V}}}_{e}\times {\boldsymbol{B}})﹩, where the shaded area represents its errors; (h) the electron energy gain per cyclotron period; (i) the relative strength of the electric and magnetic force in the electron fluid rest frame. The colored shaded regions in panels (h) and (i) represent the uncertainty in the calculation based on the uncertainties in the particle moments and electric field. The power spectral densities of (j) the electric field and (k) the magnetic field; (l) the planarity of polarization; (m) the ellipticity. The black dashed lines in panels (j)–(m) represent ﹩{f}_{0}﹩ = 1.4 Hz, corresponding to the lower frequency bound of the enhanced electromagnetic fluctuations in the reconnecting current sheet (RCS). All the vectors are displayed in the LMN coordinates.
