Fig. 21From: Swarm Thermal Ion Imager measurement performanceTIIÂ MCS (left) and EES (right) model images for a 1160Â K mixed ion population rammed at 7.6Â km/s consisting of \(\textrm{H}^+\), \(\textrm{O}^+\) and \(\mathrm{{O}^+}_2\) in relative concentrations of 0.4, 0.5 and 0.1, respectively. A satellite floating potential of - 1.2Â V was simulated with a faceplate voltage of - 1.0Â VBack to article page
