Formula to calculate most spectral quantities

Are stored here all equations that need to be used by both the factory (to generate the spectrum) or the spectrum class (to recompute some quantities in post processing)

calc_radiance(wavenumber, emissivity, Tgas, unit='mW/sr/cm2/nm')[source]

Derive radiance (\(mW/cm^2/sr/nm\)) from the emissivity.

\[I(\lambda) = \epsilon(\lambda) \cdot L_0(\lambda, T)\]
Returns

radiance – unless unit is different

Return type

array in \(mW/sr/cm2/nm\)
