Point-spread functions, line-spread functions, and edge-response functions associated with modulation transfer functions (MTFs) of the form exp[-(omega/omega(c))(n)] are tabulated for values of the MTF index (n) in the range from n = 1.0 to n = 2.0, in steps of 0.10. The MTFs are also tabulated in this range. Measurements of any one of these four image transfer functions which agree with the tabulated valves for a given set of MTF parameters (omega(c,)n) allow the other three functions to be estimated by using these tables.
