Figure 4.22 Varying Υ (top), q ′ (middle) and i (bottom) in models of the velocity
profile of NGC 4335. Models with M• = 1 × 10 8 M⊙ are shown in each case. Top:
shows data plus models with Υ = 2, 4, and 6; Middle: shows data plus models with
q ′ = 0.95, 0.85, and 0.75; Bottom: shows data plus models with i = 65 ◦ , 75 ◦ , and
85 ◦ . Definitions of the parameters are given in the text.
