Phase effect for the brightness coefficient of the central disk of Saturn and features of Jupiter's disk

Abstract

Spectral reflectivities ϱ(λ) of the features on the disk of Jupiter (NTrZ, NEB, EZ, SEB, STrZ) and the center of the disk of Saturn were measured for different phase angles. The phase dependence of ϱ(λ) is shown to correspond to the shape of the phase function.
