### Do someone knows the units of the spectra provided here ? It seems obvious enough that it's said nowhere, but even Wikipedia and other sites are quite blurry on this point.So, is it power (W), radiance($\phantom{\rule{mediummathspace}{0ex}}\mathrm{W}/{\mathrm{m}}^{2}\mathrm{s}\mathrm{r}$), or something else ?
