Hi, everyone. I am looking for both a graph and numerical values of the SPD (spectral power distribution) of illuminants D55 and D65 but haven't had much luck. The information I need is the power distribution for wavelengths across the visible spectra in 5 to 10 nm increments. I would like to have both the numerical values and also a graph showing this power distribution. Is anyone aware of where I can find this information ? Thank you in advance, Joseph.
