I'm looking at the formulas for CIELUV color space on Wikipedia.

https://en.wikipedia.org/wiki/CIELUV

The article says, "The quantities u′n and v′n are the (u′, v′) 
chromaticity coordinates of a "specified white object" – which may be 
termed the white point – and Yn is its luminance."

I have a D65 whitepoint:

     #declare XYZWhiteReference = color <95.047,100.000,108.883>;

Which of these values is u'n, v'n and Yn?

Mike
