- healpy.pixelfunc.fit_dipole(m, nest=False, bad=<class 'Mock'>, gal_cut=0)¶
Fit a dipole and a monopole to the map, excluding bad pixels.
Parameters: m : float, array-like
the map to which a dipole is fitted and subtracted, accepts masked maps
nest : bool
if False m is assumed in RING scheme, otherwise map is NESTED
bad : float
bad values of pixel, default to UNSEEN.
