Left, from top to bottom: power per unit mass (J^inc, Eq. (184)) and power per unit volume (J^inc, Eq. 183) of a monochromatic incident flux normalized by their maxima and plotted as functions of the normalized spatial coordinates X (the direction of the star is along the horizontal axis) and Z (the spin axis is along the vertical axis). The planet is represented by a green disk of unit radius. The flux, of wavelength λ, propagates in an atmosphere assumed to be homogeneous in composition (C_G = C₀) and characterized by the ratio H/R = 0.1. The optical depth is given by τ_λ = 0.2. Right, from top to bottom: power per mass unit (J^rad, Eq. (206)) and power per volume unit (J^rad) of a monochromatic flux radiated by the ground, normalized by their maxima, and plotted as functions of X and Z, with τ_λ = 0.5.
