Full WRS Scene - A full WRS scene with overlap is 375 ETM+ scans. A nominal scene without overlap is 335 ETM+ scans. Due to a movement of the bumpers, which resulted in a larger turn-around interval and an increase in the nominal number of minor frames per major frame (from 7,423 to 7,473), the nominal size of a scene without overlap may decrease. Further bumper wear changes may decrease the number of scans without overlap. The number of overlap scans will increase to compensate for the decrease in the non-overlap scene size.
