Example galaxy: the best-fit rotation curves of the dwarf galaxy IC 2574 using eight models with/without ΛCDM priors. Blue, green, purple, and black lines represent disk, gas, bulge (if present), and dark matter contributions, respectively. Solid red lines are the total rotation curves, and the shadow regions reflect 1σ (dark) and 2σ (light) confidence levels.
