cwitools.modeling.fit_model2d

cwitools.modeling.fit_model2d(model_func, model_bounds, xx, yy, zz)

Fit a Gaussian or Moffat PSF

Parameters:

• model_func (callable) – The model function, of form f(parameters, x)
• model_bounds (list) – List of tuples representing (lower, upper) bounds on the model parameters. e.g. [(0,1), (-1,-1), … ]
• xx (numpy.ndarray) – Input x position meshgrid
• yy (numpy.ndarray) – Input y position meshgrid
• zz (numpy.ndarray) – Input data to fit to (e.g. flux)

Returns:

The result of the fit.

Return type:

scipy.optimize.OptimizeResult
