fit_polynomial_to_log_radial_intensity

sunkit_image.radial.fit_polynomial_to_log_radial_intensity(radii, intensity, degree)[source]

Fits a polynomial of a given degree to the log of the radial intensity.

Parameters:
  • radii (astropy.units.Quantity) – The radii at which the fitted intensity is calculated, nominally in units of solar radii.

  • intensity (numpy.ndarray) – The 1D intensity array to fit the polynomial for.

  • degree (int) – The degree of the polynomial.

Returns:

numpy.ndarray – A polynomial of degree, degree that fits the log of the intensity profile as a function of the radius.
