Notes.
I(μ)/I(1) = 1 − μ + uaμ + ub(1 − μ)2, where I(1) is the specific intensity at the centre of the disk and μ = cosγ, γ being the angle between the surface normal and the line of sight; u + = ua + ub and u − = ua − ub.
Radius and mass of Jupiter taken as 71492 km and 1.8992 × 1030 g, respectively (Lang 1999).
