Synthetic brightness map (linear stretch) of Vega for our best‐fitting parameters: ﹩\omega =0.91﹩, ﹩\theta _{\mathrm{equ}\,}=3.329﹩ mas, ﹩T^{\mathrm{pole}\,}_{\mathrm{eff}\,}=10,150﹩ K, ﹩\mathrm{log}\,( g) _{\mathrm{pole}\,}=4.10﹩. For this model, Vega’s pole is inclined ﹩5^{\circ }﹩ toward a position angle of ﹩40^{\circ }﹩, with the subsolar point marked with an "x." The labeled intensity contours are relative to the maximum intensity in the map.
