MTF subsystems contributions for a push broom system.

Components	Terms	Parameters
MTF Across-Track	Satellite vibration, optics diffraction, optics aberration; detector size, CCD charge transfer, and electronic filter	Jitter, detector pitch, central obscuration, focal length, pupil diameter, aberration coefficient, detector pitch, number of charge transfer, charge transfer efficiency, and filter order
MTF Along-Track	Satellite vibration, satellite motion, optics diffraction, optics aberration, and detector size	Jitter, detector pitch, Integration time, central obscuration, focal length, pupil diameter, aberration coefficient, and detector pitch
