PlanckFunctions.jl

General description

PlanckFunctions.jl is designed to calculate the Planck's function thermal emission spectra , it's analytical derivatives and integrals.

• PlanckFunctions.jl package provide the following functions together with their first and second derivatives with respect to temperature:

  • Blackbody spectral intensity (Planck function)
  • Integral intensity within specified wavelength region
  • Two wavelength intensities spectral ratio
  • Two spectral bands integral intensities ratio
