White Point XYZ to calculate the spectrum of the fixture in the data range Input

WP XYZ calculated by CIE in the range of 380-780 nm with a step of 5 nm -

WP XYZ by CIE in the range 360-830 nm in increments of 1nm -

Capture Conditions White Point XYZ:	X	Y	Z
Viewing Conditions White Point XYZ:	X	Y	Z
Default field XYZ Viewing Conditions are filled with values for the illuminant D50. After copying only Reset button will return the value of WP Viewing Conditions XYZ D50 back.

No mistakes mistakes. These buttons are designed to simulate the operation of a chromatic adaptation and without various programs. The default mode is activated without errors, but you can turn on and mimic mistakes ColorLab and Argyll errors
