3.2.5. CBR anisotropy harmonics
The l distribution of the CBR harmonics Cl depends on
many cosmological parameters. Precise measurements of
the harmonics will allow
an accurate determination of the cosmological
parameters up to geometrical degeneracy
(Zaldarriaga et
al. 1997;
Efstathiou & Bond
1999;
Eisenstein et
al. 1999).
At present the data do not give any constraint on
, but on some combination of
and
;
so we defer the discussion to the next section.
