Images that wrap 360 are good for optimizing d and e
Plus, that have static features for an even spread of cp's.

Subject: [PanoToolsNG] d e parameters
How commonly do people find they need to allow non-zero d and e parameters
(which change the center of the radial aberration coefficients a, b, and
c) for rectilinear lenses? How large of a shift is typical? Does anyone
have recommendations for good test images to assess whether d and e should
be nonzero (standard "building at a distance"?).
