... Image formation is typically described as a linear process. ... where, for 2-dimensional systems, the object coordinates are and the image coordinates are . Such a general description of a linear system is termed shift-variant, because the shape of , the impulse response (or point spread function, PSF), might change as the object position, , is shifted. ... Hence, the exit pupil geometry changes with field position, so the system response changes with field position (i.e., is shift-variant). ...

The coordinate systems must be updated when the data (pixel data, other keywords, related tables) are altered (eg. rebinning of the image). ...

... This is generally not a problem for point sources but for regions of extended emission it can cause an extracted spectrum to be a mix of flux from different areas of an object. It may be possible to disentangle the true sky emission by simultaneously fitting different spectral files. In this case an ARF giving the expected contribution (effective area) of flux received in one area from a different area is needed. ...
