5. Examples of source emission comparisons at LE

A simplified, pragmatic method for calculating the luminances L _B and L _R of sources to be compared with LE, based on illuminance data.

L _B = E _B / Max(Ω _Bmax , Ω(α)) where Ω _Bmax ≈ π/4 γ ² _{ph max} ≈ 10 ^–2 sr with γ _{ph max} = 100 mrad

L _R = E _R / Max(Ω _Rmax...
