Azimuthally averaged profiles of images shown in Appendix A for PSZ2 G098.62+51.76. The dashed black lines represent the theoretical injected profiles. The sampled pre-injection and post-injection profiles are shown with black and coloured dots (see the total injected flux density in the legend), respectively. The grey vertical line indicates r = 3r_e. The grey horizontal line indicates the global 1σ noise level.
