Module API

b_sersic(n)

fit_sersic(radial_flux_density, r, w=None)

fit_sersic_profile(surf_bright_profile, cluster_image=None, image_centroid=None)

get_galaxy_profile_fit_morphometric_features(surf_bright_profile, group_name='model', name_flag=None, cluster_image=None, image_centroid=None)

Function to extract galaxy morphometric features for :.... . The try/except statement allows to return np.nan features

Parameters:

surf_bright_profile : :class: asterism.core.photometry.surface_brightness_profile.ImageBrigthnessRadialProfile

instance object for the surface brightness profile

group_name : str

the group name for the features (see MorphometricFeatures)

name_flag : str

the flag name for the features (see MorphometricFeatures)

Returns:

MorphometricFeatures : MorphometricFeatures

The class storing the features with their names and dtypes
