Abstract
A method of quantifying a shape of a surface includes measuring an elevation (z) of the surface at a plurality of locations in an x-y plane of the surface. The measurement data is fit to a series expansion in terms of one or more base functions that include a series expansion fit. A vector of shape coefficients are calculated from the series expansion fit. A vector of shape coefficients are output.
