Selection of the solution for September 12, 2007 (~2000 UT). A non-stationary method is compared to a stationary one for several versions of calculations (see text). The minimal Δ and the corresponding neutral gas density ρ, exospheric temperature Tex, vertical plasma drift W, and ρ/Δ are given. Three maximal ρ/Δ and the corresponding ρ values are given in bold.
