polalm
decomposes an input CMB temperature map into its spherical harmonic
coefficients and/or power spectrum:

(13) 
where K.
and
calculates decomposition coefficients of scalar and pseudoscalar
potentials (E and Bmodes) for Q and Umaps:

See other details in the correpsnoding paper of GLESP 2.0.
To decompose an input maps for harmonic coefficients, polalm
processes the FITS Binary map with position and temperature, or Q and U
Stokes parameters
(

)
in 3 sections:

, the centerposition of the rings as a function of
the polar angle (nx positions),
 nx numbers with the number of pixels, nphi, in the corresponding
ring,

organized in one row using Point 1 as the major index
and Point 2 as the minor index.
Examples
 Map decomposition for its angular power spectrum and/or
spherical harmonic coefficients (map):
