First row: Gaussian CMB realisation (left), the filtered version (middle), and the square of the filtered map (right). The orange ellipse denotes the random dipole direction observed on large angular scales. For the squared map, dark blue corresponds to zero temperature, while for all other maps dark red and dark blue correspond to the largest negative and positive fluctuations in the map. Second row: product of the Gaussian map (left) and the squared filtered map (middle) generates the non-Gaussian contribution (right) that enhances the dipole in the power distribution. Third row: combination of the original Gaussian map (left) and the non-Gaussian term (middle) scaled by the factor β_{dimensionless} = 1.77 × 10⁸ yielding a non-Gaussian map (right) with enhanced dipole modulation and a hot spot with excess kurtosis shown in the blue circle. Last row: as in the third row, but for scales ℓ = 100−200 only. The value of β is exaggerated here in order to make the effect visible by eye.
