Hello everybody,

I have one question concerning the radius normalization. For the poly5 model there is a reference to imatest.com/docs/distortion.html where it says, /"r_d / is the distorted (measured) radius normalized to the center-to-corner distance". Is this the case for all models? So is the radius radius equal to 1 for the corners which would mean that the radius can never become bigger than 1?

Regards and many thanks in advance,
Philipp
