Confidence areas in the log C − log M_h/h^-1 plane and in the M_∗ − M_h/h^-1 plane for the dynamical fit to the rotation curve using a NFW dark matter halo profile: 68.3% (darker regions, blue in the online version), 95.4% (magenta) and 99.7% (lighter regions, cyan). The mass distribution is that given by the BVIgi colors for the areas shown in a) and b), and by the BVI colors for the areas in c) and d). In panels a) and c) we show the C–M_h relation (solid line) and its dispersion (dashed line) for ΛCDM cosmology. In panels b) and d) the dash-dot line indicates the most likely stellar mass according the synthesis models, which rely on the colors shown next to panel labels.
