Comments
The data is sparse--perhaps due to an intent to provide a simple opportunity to work a mosaic. There are 3 primary issues with my rendering. One of the two blue left hand frames is fogged--I am not aware of any PI tools that would correct that without being too clumsy, so it had to be rejected because it created a nasty gradient in the result. I balanced the intensity of the frames as a group before merging the image pairs--perhaps I should have first balanced the side frames pairwise, then balanced the resulting merged frames. Lastly, my application of PI's CosmeticCorrection process failed to remove a number of hot pixel groups--more attention is needed in that regard.
