Panel a: three-velocity v (solid black line) and sound speed a (long dashedblue line) as functions of r. Panel b: comparison of velocity distribution of thermally driven or ℓ = 0 jet (dashed red line) and the radiatively driven jet (solid black line); panel c: Θ;panel d: E; panel e: Γ and panel f: as a functionof r. All the plots are for E = 1.04 and radiatively driven jet is for ℓ = 0.8.
