Fig. 2: Typical mass-energy spectrum of the dispersed structures.
From: Detection of magnetospheric ion drift patterns at Mars

The dispersed ions with energy ranging from 20-200 eV were \({{{{{{\rm{H}}}}}}}^{+}\) with m/q = 1, with a possible small fraction of \({{{{{{\rm{H}}}}}}}_{2}^{+}\) or \({{{{{\rm{H}}}}}}{{{{{{\rm{e}}}}}}}^{2+}\) (m/q = 2). Integrated time is 4 sec. The color represents the DEF of ions.
