Detailed Description

Calculates a series of affine transformations from the measured coordinates of the up to 90 fiducial marks on a complete (stiched) apollo panoramic cube

Description: The 90 Fiducial marks effectively divide a complete (stitched) apollo panormaic cube into 44 rectangular regions. 42 of these represent the same period of time, T, the center two are 0.5T. This class uses up to 44 2 dimensional affine transformations linked together with first order continuity conditions at the boundaries to enforce consistent line scan durations and correct warping in the film.
