BiSpectrum_Distance¶

class turbustat.statistics.BiSpectrum_Distance(data1, data2, nsamples=100, fiducial_model=None)[source] [edit on github]¶

Bases: object

Calculate the distance between two images based on their bicoherence. The distance is the L2 norm between the bicoherence surfaces.

Parameters:	data1 : FITS hdu Contains the data and header of the image. data2 : FITS hdu Contains the data and header of the image. nsamples : int, optional Sets the number of samples to take at each vector magnitude. fiducial_model : Bispectrum Computed Bispectrum object. use to avoid recomputing.
