This is a plate model of all the time we were allowed to take picures in the high mass case, with the camera pointed directly below the spacecraft, or nadir, the whole time. Blue is 0 degrees emission angle (that's what we want - it means we are looking directly perpendicular to the surface). Red represents 90 degrees emission angle, and green is a gradation beween blue and red. We use this particular model as a control when we make alterations, in order to see if we improved the model.
