Web摘要： We develop formulas for Gaussian beam transformation with fixed total distance between beamwaists, and consider the use of cylindrical lenses or mirrors to produce beams which are not symmetric about the axis of propagation. WebSep 23, 2003 · In Section 2 we describe the method for fitting a GMRF to the data described above. Section 3 then demonstrates how the disaggregation is performed and shows results. Finally, Section 4 is a short discussion. 2. Model. To fit a GMRF, we assume that the empirical correlations of the observed data are the correlation function of a Gaussian …

There are three unknown parameters for a 1D Gaussian function (a, b, c) and five for a 2D Gaussian function (;,;,). The most common method for estimating the Gaussian parameters is to take the logarithm of the data and fit a parabola to the resulting data set.
