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.
