To me it looks like the Chromaticity values are the CIE x, y and z
tristimuli values, and Luminance is the CIE Y value.
To convert these values to RGB, I think you have to multiply each of the
chromaticity values by the luminance value.

The long list of numbers are the reflection values for each wavelength.

I don't think any of these values has anything to do with "diffuse
coefficients".
