I'm not sure if this is the right forum...

How can I do calibration (radiometric and geometric) of Voyager images? Does anyone know?

Hi, don't forget that Voyager cameras are vidicon tubes and have very large geometric distortions, especially near the edges. These distortions are different in every frame and are affected by image content, electromagnetic environment it was taken, etc. Using reseaux, these distortions are calculated and corrected for each frame. Without correcting this geometric distortions it is not possible to make good mosaics.

But if the image is uniform and does not have many regions which are very different in brightness you may use a single matrix for correction, one for each of the four Voyager cameras, which I can send you if you wish.
