Module planck 

Functions

dlpdlt

Computes the logarithmic derivative of the Planck function Bnu wrt T (i.e. d ln(Bnu) / d ln(T)) as a function of wavelength and temperature

dplanck

Computes the logarithmic derivative of the Planck function Bnu wrt wavelength (i.e. d ln(Bnu) / d ln(lambda)) as a function of wavelength and temperature

planck

Computes the Planck function Bnu = (2 h \nu^3/c^2)/(exp(h \nu/kT) - 1) as a function of wavelength and temperature. Output units are W/m**2/Hz/sr.
