10 pages,10 figures. Has better density accuracy near the galaxy center by moving the segment rod to the segment centroid, and reducing the allowable errors for the speed matches. Some small changes in text, table, figures

Given the dimensions(including thickness) of an axisymmetric galaxy, Newton's\nlaw is used in integral form to find the density distributions required to\nmatch a wide range of orbital speed profiles. Newton's law is not modified and\nno dark-matter halos are required. The speed distributions can have extreme\nshapes if they are reasonably smooth. Several examples are given.\n
