 *
 * NAME: ViirsBandModDG.h
 *
 * DESCRIPTION: Subclass of ViirsBandMod object class that provides data structures
 * and processes common to all dual-gain moderate resolution bands required to
 * support calibration processing. It is the base class for the the
 * ViirsBandModDGRsb and ViirsBandModDGTeb object classes.
