We use two types of normalization, one based on the total spectrum from 250 - 2500 nm, and the second based on 250 - 1100 nm. In each case, we calculate the normalization, or scaling factor, by comparing the total simulator irradiance with the total irradiance for the appropriate standard (ASTM or CIE) curve. Our comparison curves show the simulator multiplied by the scaling factor so the displayed simulator curve has the same total irradiance as the relevant standard curve over the spectral region of interest.
