fit_dipole
(m, nest=False, bad=-1.6375e+30, 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
.- gal_cut : float [degrees]
pixels at latitude in [-gal_cut;+gal_cut] degrees are not taken into account
Returns: - res : tuple of length 2
the monopole value in res[0] and the dipole vector (as array) in res[1]
