on the following paramters might be changed in the denseoffset steps:
=======================================================================
        if self.frameOffsetMatching == False:
            self._insar.frameRangeOffsetMatchingMaster = offsetMaster[2]
            self._insar.frameAzimuthOffsetMatchingMaster = offsetMaster[3]
        self._insar.frameRangeOffsetMatchingSlave = offsetSlave[2]
        self._insar.frameAzimuthOffsetMatchingSlave = offsetSlave[3]


Therefore these denseoffset steps could be moved to after 'frame_mosaic' step
