map1 : float, array-like shape (Npix,) or (3, Npix)
Either an array representing a map, or a sequence of 3 arrays
representing I, Q, U maps
map2 : float, array-like shape (Npix,) or (3, Npix)
Either an array representing a map, or a sequence of 3 arrays
representing I, Q, U maps
nspec : None or int, optional
The number of spectra to return. If None, returns all, otherwise
returns cls[:nspec]
lmax : int, scalar, optional
Maximum l of the power spectrum (default: 3*nside-1)
mmax : int, scalar, optional
Maximum m of the alm (default: lmax)
iter : int, scalar, optional
Number of iteration (default: 3)
alm : bool, scalar, optional
If True, returns both cl and alm, otherwise only cl is returned
pol : bool, optional
If True, assumes input maps are TQU. Output will be TEB cl’s and
correlations (input must be 1 or 3 maps).
If False, maps are assumed to be described by spin 0 spherical harmonics.
(input can be any number of maps)
If there is only one input map, it has no effect. Default: True.
regression : bool, scalar, optional
If True, map average is removed before computing alm. Default: True.
datapath : None or str, optional
If given, the directory where to find the weights data.
