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.
