 * NAME: ViirsBandMod.h
 *
 * DESCRIPTION: Subclass of ViirsBand object class that provides data structures
 * and processes common to all moderate resolution (MOD) bands required to support
 * calibration processing. It is the base class for the the ViirsBandModDG and
 * ViirsBandModSG object classes.
