Examples of maps at two specific multipoles in the reference system with the z axis parallel to the observer velocity (left column) and in Galactic coordinates (central and right columns). According to Planck Collaboration I (2020), we adopt l = 264.021° and b = 48.253° for the dipole direction in Galactic coordinates. We display the temperature pattern for a BE-like distortion with μ₀ = 1.4 × 10⁻⁵ (top row), a Comptonization distortion with u = 2 × 10⁻⁶ (central row) and the CIB distribution function with best-fit amplitude value I₀ = 1.3 × 10⁻⁵ added to the blackbody one (bottom row), minus the temperature pattern coming from the blackbody. The considered frequency and multipole is given above each map. Maps are in equivalent thermodynamic (or CMB) temperature.
