Example rotation curve fits and halo density profiles. Top: rotation-curve fits with adiabatically compressed DM halos for NGC 3198 (left) and UGC 06786 (right). Green, blue, and purple dotted lines represent the contributions of gas, disk and bulge, respectively. Black solid lines show the best-fit compressed DM halos, while black dashed lines show the corresponding initial NFW halos. Red solid lines show the expected total rotation curves, which match the data better than Fig. 1 after adjusting the fitting parameters. Bottom: density profiles of the compressed (red lines) DM halos and associated initial NFW halos (black lines). Blue lines show a parametric fit to the compressed DM halo using the (α, β, γ) model with α fixed to unity. The best-fit parameters for stellar disks, bulges, prior-compression and post compression DM halos are presented in Table A.1. The complete figure set of 125 rotation curve fits and density plots are available in the SPARC database.
