pfly you are correct an unposted Airbus A300-600 to add to the collection.
Most of the technical data about satellites make is not unfortunately written in a manner that is easily understood. It often sounds more complex than it really is.

In the old days of black and white photography it was a Manufacturer goal to make a film that was equally sensitive to all colors. This goal was never really achieved. Electronic imaging gets closer because any imbalance in sensitivities can be digitally processed out. A panchromatic image would be the ideal black to white image supporting all of the subtleties of a true gray scale. In the satellite image reconstruction, which assumes a stationary image, white is equivalent to equal amounts of red, green and blue. When you superimpose the displaced image the color and black and white image processing is making wrong assumptions about both the foregound and background actual colors.
