function gauss2dfit

Fit a two-dimensional gaussian to a rectangular grid (i.e. an image).

Syntax
result = gauss2dfit(image, errors, estimate [, chisq])

Arguments

image:   The image to be fit

errors:   The errors in the image values

estimate:   Initial estimate for the fit of the form [Offset,Max,x0,y0,fwhm1,fwhm2,angle]

chisq:   If set to a named variable, the variable is overwritten with the chi-squared of the fit.

Returns
The returned vector contains the best-fit parameters in the form [Offset, Max, x0, y0, fwhm1, fwhm2, angle, d_Offset, d_Max, d_x0, d_y0, d_fwhm1, d_fwhm2, d_angle]
