This hypothesis, suggested by conformal gravity, does allow good fits to the galactic rotation curves of the galaxies we study, which have a wide range of luminosities. However, the universality one might have expected of the parameter describing the strength of the linear potential does not emerge. Instead, a different regularity is seen.10 pages of text; 2 pages of figures available from CEC (carlson@cebaf1.cebaf.gov) via post or e-mailAstrophysicstext
