Enclosed mass profiles for the MOND missing matter using a simplistic subtraction approach (see Sect. A). Dots show data from X-ray observations only, while triangles show those adding the SZ effect. For each cluster, the left panel shows the results for the isolated case with no EFE, while the right panels consider a basic implementation of the EFE from the large-scale structure using MOND external field strengths of 10% (red), 30% (blue), 50% (orange) and 100% (green) a₀. In most cases, considering a relatively strong EFE leads to physical (non-decreasing) enclosed mass profiles; exceptions are A644 and A2319 that have clear signatures of merger activity and may be out of dynamical equilibrium.
