However, this is non-normalized emission data. In other words, the WhitePoint is not normalized to Y=100 and the display WhitePoint will likely not match a standard Illuminant.
When you open the cxf file, PatchTool will ask you to select an Illuminant, because it expects a reference Illuminant, which is always required for reflectance measurement. If your display is nearly spot-on a standard Illuminant (i.e. D50, D65), this selection makes sense. In most cases it does not.
Danny, Thank you for helping clear up matters! Can the Display-Reader module be used to measure the whitepoint for display measurement data? I'm thinking along the lines of showing a white patch, measuring it, and using that as the whitepoint value.
