The lenses for each sensor in the array are closely matched, except for the lenses for UV and Thermal bands. There are small differences (or large in the case of UV or Thermal bands) in the magnification factor for each lens. To match the magnification, or field of view, of all bands to the master camera, a scaling value us supplied in the alignment file. A number greater than 1.0 magnifies the image (reduces field of view) and a number less than 1.0 shrinks the image. Typical values range from 1.01 to .98 for matched lenses. In the case of thermal and UV bands the numbers must be larger because the lenses are not well matched.
