This zipped .tif of a Granger Rainbow has my scanner profile assigned to it:

It's a LUT-based profile of a Nikon scanner using the Hutchcolor
target and set on -qh.  The average and peak errors reported at the
end seemed okay - they were near 1 and 5.  I tried a regular IT8
target on the same scanner, as well as a reflective target on an Epson
scanner, and got a fairly similar "eye" shape in the blues on a
Granger.  I don't really know enough to judge whether what I see in
the rainbow is a concern or not.
