cwitools.modeling.gauss2d_sym

cwitools.modeling.gauss2d_sym(params, xx, yy)

Symmetric 2D Gaussian profile in the form f(parameters, x)

I(x) = I0 * exp(-[(x-x0)^2 + (y-y0)^2] / (2*sig^2) )

Parameters:

• params (list) – 2D Gaussian parameters (I0, x0, y0, sig_x, sig_y, theta) I0 - amplitude x0, y0 - x and y means sig - standard deviation
• xx (numpy.ndarray) – 2D meshgrid of x position
• yy (numpy.ndarray) – 2D Meshgrid of y position

Returns:

The 2D Gaussian model output

Return type:

numpy.ndarray
