normalize_fit_radial_intensity

sunkit_image.radial.normalize_fit_radial_intensity(radii, polynomial, normalization_radius)

Normalizes the fitted radial intensity to the value at the normalization radius.

The function assumes that the polynomial is the best fit to the observed log of the intensity as a function of radius.

Parameters:

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

• polynomial (numpy.ndarray) – A polynomial of a given degree that fits the log of the intensity profile as a function of the radius.

• normalization_radius (astropy.units.Quantity) – The radius at which the fitted intensity value is normalized to.

Returns:

numpy.ndarray – An array with the same shape as radii which expresses the fitted intensity value normalized to its value at the normalization radius.
