<p>
<img src="gauss.png" align="right">
Creates an elliptical Gaussian. This is defined by respective FWHM1 and FWHM2, axis position angle (in degrees) and Gaussian center position (x, y) in the array. Optional keywords are naxis1, naxis2 which determine the size of the array. If not set, the size of the array is determined from global variables. If only one argument is given, return the value of a gauss as determined from exp(-4ln(2)*x^2).
