Formal solution of the radiative transfer equation

For an outward ray through a nonscattering atmosphere,

I_{ν} (0, μ) = I_{ν} (τ_{b}, μ) e^{- τ_{b} / μ} + \int_{0}^{τ_{b}} B_{ν} [T (t)] e^{- t / μ} \frac{d t}{μ} .

Eddington-Barbier relation

When the source function varies approximately linearly with optical depth, the emergent intensity obeys

I_{ν} (0, μ) ≃ S_{ν} (τ_{ν} = μ)
