Synchrotron angular spectra at various Galactic latitudes and frequencies.

We study the angular power spectra of the polarized Galactic synchrotron emission in the range 10≤l≤800, at several frequencies between 0.4 and 2.7 GHz and at several Galactic latitudes up to near the North Galactic Pole. We properly distinguish between the various polarization spectra that can be defined and measured, including the C[sub PIl] spectrum which is insensitive to the polarization direction. © 2002 American Institute of Physics.
