| Abstract: |
When whole-sky linear polarization is expressed in terms of Stokes parameters T_Q and T_U, as in analyzing polarization results from the Differential Microwave Radiometers (DMR) on NASA's Cosmic Background Explorer (COBE), coordinate transformations produce a mixing of T_Q and T_U. Consequently, it is inappropriate to expand T_Q and T_U in ordinary spherical harmonics. The proper expansion expresses both T_Q and T_U simultaneously in terms of a particular order of generalized spherical harmonics. The approach described here has been implemented, and is being used to analyze the polarization signals from the DMR data. |
