WebCTF, at any frequency can be expressed as a summation of harmonic components. These components are weighted by two multiplicative factors in the summation: their relative strength in the input waveform and the MTF of the system under test at each harmonic frequency. This process yields an expression3 for CTF in terms of MTF (4) Web(This field can be used to divide the data set into multiple optics groups: separately import each optics group with its own name, and then use the Join star files jobtype to combine the groups.

WebMTF is defined as the Fourier transform (FT) of the point spread function (PSF). This concept applies to a linear system that is shift invariant. In practice, MTF is usually measured in two orthogonal directions using FT of the line spread function.
