Single-spacecraft observation. Example from 7 October 2015, showing a case when magnetosheath plasma was found in the −E hemisphere. (a) Logarithm of the differential energy flux of the ions in units of eV/(cm²s sr eV), (b) logarithm of the differential energy flux of the electrons in units of eV /(cm²s sr eV), (c) normalized integrated electron energy flux F_e, (d) magnetic flux density components, (e) normalized z_MSE coordinate cos θ, (f) F_e (color-coded) at the positions of the observation in the y_MSE − z_MSE plane, and (g) F_e (color-coded) at the positions of the observation in the x_MSE− z_MSE plane. The magnetosheath is characterized by a higher electron flux F_e, as shown in panels c, f, and g. The −E hemisphere corresponds to cos θ < 0.
