Dependence of the peak amplitude parameters at ℓ = 492 (k_pix = 21) measured by the updated code on the rebinning strength. Left panel: input (black dotted lines with squares) and measurements with three different rebinning with error bars (scatter of 500 realizations): no rebinning (256 pixels on the azimuthal grid, blue), original rebinning (64 pixels, green), and extra rebinning (16 pixels, red). Right panel: ratio of the amplitude to the input. The numbers are the grid number and the average ratio of six peaks. The input parameters are identical to those in Fig. 2.
