A mistake in the geometric descriptions
of the UTT was found:
In contrast to the lower left corners
of the patches for the gray scales the
center of the patches are described.
Now it is added a sentence at the top of
the gray scales description to correct that.
Change of slanted edge contrast from
delta L* 18 (L* min 44, L* max 62)
to the one specified in ISO 16067-1 for
delta L* 29 (L*min 34, L*max 63).
