caption: MOND fits to the observed rotation curves of early-type disc galaxies. Data points show the observed rotation curves and error bars give the combined uncertainties due to the measurement errors and kinematical asymmetries. The grey shaded bands give the allowed range due to inclination uncertainties. Thin black solid, dashed and dotted lines give the contributions from stellar bulge, disc and gas, respectively. The thin green (grey) line gives the Newtonian sum of the individual components and the bold blue (grey) lines gives the total MOND rotation curve, assuming the interpolating function μ from equation (3).
