Pixel map of count-rate-derived potassium abundances. The image is linearly
scaled such that the maximum pixel value (255) corresponds to a potassium
abundance of 2430 parts per million (ppm). Conversion from Digital Number
(DN) to science value is given by the equation:

SCIENCE_VALUE = (DN * 9.530)
