MCMC fit results for the isolated case (Eq. (9)). From left to right: acceleration profiles, enclosed mass profiles, circular-velocity profiles, and relative residual difference. In the first three panels, observed data (black points) are fitted with a mass model (black line) that includes the contribution of visible baryons (red line) and missing mass (blue line). We fit the data up to 1 Mpc (black points), where the hydrostatic bias should play a minor role, and then extrapolate the model to larger radii (grey line) to estimate the maximum hydrostatic bias in MOND (rightmost panels).
