The Cosmic Microwave Background is often characterized by the Angular Power Spectrum of its
Anisotropy. The spectrum shows the calculated coefficients
of a Multipole Expansion of the temperature over the spherical
coordinates. In effect, it shows at what angular distances across
the sky, calculated (Wien's Displacement Law) temperatures are similar. A
The CMB's Angular Power Spectrum of temperature is often cited, but a similar spectrum of CMB Polarization and/or Gravitational Lensing is also used. harmonics,cosmology,CMB,function)Referenced by:
