Product Name
Predicted Sunyaev-Zeldovich Power Spectrum


The angular power spectrum due to the Sunyaev-Zeldovich effect as predicted by Komatsu and seljak, 2002 are supplied for each of the five WMAP observing frequencies.

The spectra are supplied in a single ASCII text file with six columns:

  1. The multipole moment l
  2. The K-band spectrum (22.8GHz) in μK2
  3. The Ka-band spectrum (33.0GHz) in μK2
  4. The Q-band spectrum (40.7GHz) in μK2
  5. The V-band spectrum (60.8GHz) in μK2
  6. The W-band spectrum (93.5GHz) in μK2

The spectra were computed with the following parameter assumptions:

h =0.722
ns =0.972

They are supplied in the form: l (l + 1) Cl / π2
