Target is CMYK, 8 rows of patches, 33 patches per row = 264. 
The GRAD file next to it has 8 lists that say C,LC. M, LM etc. 
It will print the target with Colorbase. The split to the 8 
channels will be based on the CMK percentages in the target, Y 
isn't split.

an excerpt from the Colorsync list:

Well, a simple look at the reference data lets me draw the 
conclusion that
this is more a linearisation tool than a calibration tool.

The patches in there look like cyan, magenta, yellow and grey 
patches.
Just not enough colors to build a lookup-table.
