Same polarity image distortion. a An example of a synthetic intense flux patch at the CMB. b Its root at mid-depth rotated by 45°. The patch is modeled by a Gaussian with standard deviation equals to 1. c Correlation between the intense flux patch in a and its root rotated by α. The black dashed line shows the maximum acceptable rotation β≈31.7° for correlations higher than 0.5
