A simple example of return mapping
This example illustrates return mapping for multipole number ℓ = 6, utilizing the WMAP ILC map data. The analysis focuses on the multipole expansion, specifically examining the phases of m=0, m=1, m=2, and m=3. Coordinate points such as (1.2783, 5.9600) and (3.1416, 1.2783) are crucial for demonstrating phase relationships in the context of angular power spectra. The resulting mappings provide insights on multipole behavior and their phase relationships in the cosmic microwave background field.
