Spatial distribution of the ratio of electron-to-ion temperature, T_e/T, from a model calculation with τ_e−i( = T_e/T | ₀) = 0.1 and ψ = 0.1. The orbital (x − y) plane is shown at phases, φ = 0.5 (top) and 1.0 (bottom). All plots show the full x − y extent of the domain (see Sect. 2.2). Note that values of T_e/T in the un-shocked winds are plotted as zero to aid visibility but are taken to be unity in the X-ray calculations.
