The dark lines represent the models with the velocity field running from positive to negative velocities (which produces the minimum result in this case), the light lines show the values with the sense of the model velocities reversed. The three lines in each set represent the weighted-mean residuals between the data and the M• = 0 (solid lines), M• = 1 × 10 8 M⊙ (dashed lines), and M• = 9 × 10 8 M⊙ (dash-dot lines) models. 192
