We did test several tubes including a 21AXP22. Attached are several different
charts and graphs: The first is the spectrum response of the 21AXP22 taken with the EYE-ONE Pro Spectroradiometer. This is a gray faced tube as I remember. The second and third are both CIE charts comparing the color
coordinates, some measured and some published, of various color sources and
defined colors. Disregard "RX43" in the title of the third one.
Hope this helps answer some of the questions. Cliff
