Points with error bars are the high‐resolution rotation curves of LSB galaxies taken from de Blok & Bosma (2002). The dashed lines are NFW fits obtained by adjusting one parameter: c varies between 13.5 and 17 for these galaxies. The solid lines are our halos with tangentially oriented velocity ellipsoids: ﹩\zeta _{0}=20^{\circ }﹩ for NGC 5750 and NGC 100, and ﹩\zeta _{0}=50^{\circ }﹩ for NGC 1560 and NGC 5023. The dotted curve in the top left panel represents our halo with a spherical velocity ellipsoid, i.e., ﹩\zeta _{0}=90^{\circ }﹩. See § 4.7 for details.
