IOW, in this case, the LT does not produce what's actually measured in the target frame of the transformation. This behavior negates the claim that the LT produces what is actually measured in the target frame. So I referred to the resultant measurement predicted by the LT as apparent. You can give it another description. I am not wedded to that word.
