In the table (below right), type in the wavelengths (in nm) and the spectral radiance (in Watts/sq.cm./ steradian/nm) measured at each wavelength. Then use the sliders to adjust the color temperature (K) and the emissivity until the blackbody curve (solid red line) passes throught the experimental data points (blue circles) as closely as possible.
