Blackbody Radiation

The blackbody spectrum is another option that can be chosen. The flux density is calculated as a function of wavelength (14) for the user-defined temperature (T).

f ($\displaystyle \lambda$) $\displaystyle \propto$ $\displaystyle {\frac{{1}}{{\lambda^5 \cdot \exp \left ( \frac{\mathrm{hc}}{\mathrm{k}\lambda \mathrm{T_{BB}}}\right )-1}}}$ (13)

h : Planck's constant h = 6, 62607 . 10-34 Js
c : velocity of light c = 2.9983 . 108 $ {\frac{{m}}{{s}}}$
k : Boltzmann's constant k = 1, 3807 . 10-23 $ {\frac{{J}}{{s}}}$
T BB : Blackbody temperature


After that calculation the flux is normalized to the magnitude given by the user.
