In such cases, we must calibrate with the smalles possible crop
factor (i.e. the largest image radius).  Then, we add camera entries
for all possible crop factors.  But still only one lens model is
necessary.

At least in one case (I cannot remember the model name), there were
different aspect ratios but the same crop factor.  Then, the same
camera and lens model can be used for all aspect ratios.

(This is certainly something to re-visit for the next database
overhaul ...)

Tschö,
Torsten.
