What formula Nuke use for Lens correction in Card Node?

Posted in: NUKE from The Foundry
In the Card node, I see that there’re 2 Lens correction models.
the first one is lens distortion with a, b & c parameters.
I assume the formula was explain in this page on PanoTools site
Am I right?

and what about the other one?
the Old distortion, with distortion and power parameter
what’s the formula that take this 2 parameters and do the lens correction?
if I were to write my own lens correction script, so I can mimic what Nuke does on Card node.

Thank you
