Special Pixels

[jlaura]

Should the these high special pixels be positive?

I don't believe so. This is the relevant excerpt from SpecialPixel.h in the isis code base:

  // 2-byte signed special pixel values
  const short VALID_MIN2     = ((short)(-32752));
  const short NULL2          = ((short)(-32768));
  const short LOW_REPR_SAT2  = ((short)(-32767));
  const short LOW_INSTR_SAT2 = ((short)(-32766));
  const short HIGH_INSTR_SAT2 = ((short)(-32765));
  const short HIGH_REPR_SAT2  = ((short)(-32764));
  const short VALID_MAX2      = ((short)   32767);

If you looking in the source, the file is isis/src/base/objs/SpecialPixel/SpecialPixel.h.
