Hi Josh,

This is right for 'ordinary' slit cameras, but not if used
with a fisheye. I suspect your distortion problems to be partially due
to nodal point errors.

The next version of Panorama Tools will include a polynomial
correction for scanning cameras (same as current radial
correction). It can be used to correct lens distortions
and color separation. Haven't yet processed your test image
though..

Regards

Helmut
