standardize_moments

scarlet2.init.standardize_moments(g, obs)

Standardize the 2nd moments to match the model frame

Adjust the spatial coordinates and deconvolved from the observation PSF to mimic moments measured in the model frame.

Parameters:

• g (Moments) – 2nd moments, measured in observed frame

• obs (Observation) – The Observation instance to derive moments from

• center (tuple) – central pixel of the source

• footprint (array, optional) – 2D image with non-zero values for all pixels associated with this source (aka a segmentation map or footprint)

• bbox (BBox, optional) – box to cut out source from observation, in pixel coordinates

Returns:

2nd moments, deconvolved, and in the coordinates of the model frame

Return type:

Moments
