Weighted average of the rescaled differential surface mass density profiles for the clusters in our sample. The black points and blue squares refer to measurements using the X-ray (all clusters except SPT-CL J0646−6236 for which we do not have X-ray measurements) and SZ centres, respectively. The blue line shows the average weighted model NFW function assuming a fixed concentration–mass relation following Diemer & Kravtsov (2015) with updated parameters from Diemer & Joyce (2019) for measurements from the SZ centres. The vertical dotted line indicates the lower limit of our fit range.
