cwitools.modeling.moffat2d

cwitools.modeling.moffat2d(params, xx, yy)

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

I(x) = I0 * (1 + ((x - x0)^2 + (y-y0)^2) / gamma^2 )^(-alpha)

Parameters:

• params (list) – 1D Moffat parameters (I0, x0, y0, alpha, gamma)
• xx (numpy.ndarray) – Meshgrid of x position
• yy (numpy.ndarray) – Meshgrid of y position

Returns:

The Moffat model output

Return type:

numpy.ndarray
