  Remarkable fit of galaxy rotation curves is achieved using a simple model
from string theory. The rotation curves of the same group of galaxies are also
fit using dark matter model with the generalized Navarro-Frenk-White profile
for comparison. String model utilizes three free parameters vs five in the dark
matter model. The average chi-squared of the string model fit is 1.649 while
that of the dark matter model is 1.513. The generalized NFW profile fits
marginally better at a price of two more free parameters.
