Comparison of the uv profiles of all the gNFW flavors adopted in our work. The data are binned so that each bin contains the same number of visibilities (here set to 2500 for plotting purposes). Before being averaged, the phase center was shifted to the position of cluster centroid to minimize the ringing effect due to non-zero phases. A model profile was not plotted for MOO J0903+1310 as the SZ signal is not detected.
