Figure 28: A comparison of the mass-to-light ratios obtained from MOND rotation curve fits
(points) with the independent expectations of stellar population synthesis models (lines) [42]. The
mass-to-light ratio in the optical (blue -band, left) and near-infrared (2.2 m -band, right)
are shown as a function of color (the ratio of blue to green light). The one free parameter of
MOND rotation curve fits reproduces the normalization, slope, and scatter expected from what we
know about stars. Not all galaxies illustrated here have both and -band data. Some have
neither, instead having photometry in some other bandpass (e.g., or or ).
