IMAGEFILES/ stores images that will be used in SPC. These images are created by process_fits, which is different for every flight mission.

The data stored in each image file contained in the IMAGEFILES/ directory is a scaled unsigned integer (2 bytes or 16 bits), with the exclusion of values less than 0. Acceptable values are from 0 to 32767.

If the source is a real (or 32-bit float) value process_fits takes the original images' data float and calculates the maximum value. Then it scales the data to spread from 0 to 32767 to maximize the accuracy of the stored data.
