The SPARC catalogue of disk galaxies contains data on both the rotation curves and the baryonic matter distributions. This data set enables an analysis to be carried out to see whether a simple weighting function applied to the matter distributions can explain the rotation curves, without the need for any dark matter. It turns out that the radial distance raised to a small negative power is such a weighting function and it is sufficient to explain the observed rotation curves. This observational result leads to a new expression for the rotation curve with only one adjustable parameter.
