PTOptimizer uses a process of trial-and-error to find the correct
parameters for FOV (field-of-view), roll, pitch, yaw, a, b, c, d & e.

Sometimes is decides that it can fit all the images together
perfectly by making the FOV incredibly small - This isn't very
helpful.

Basically, you have to be careful; you should already have a close
approximation of FOV and image position (roll, pitch & yaw) before
you optimise FOV.
