Fig. 1

Cartoon diagram of cross-sections of axis-symmetric accretion disc and the associated jet in (r, θ, ϕ coordinates). The shock location xsh, the interceptof outer disc on the jet axis (d0), height of the shock Hsh, and the outer edge of the disc x0 are marked. The semi-vertical angle of the corona is θC and for the outer disc is θD. The funnel of the corona is also shown.
