DESCRIPTION                    = "

Pixel map of silicon gamma-ray count rates. Includes contributions from the
1779-keV peak. The image is linearly scaled such that the maximum pixel value
(255) corresponds to a count rate of 2.446 counts per minute. Conversion from
Digital Number (DN) to science value is given by the equation:

SCIENCE_VALUE = (DN * 0.00959)
