Velocity field of an inclined galaxy (IC5376, i_phot = 80?). Top: SDSS composite image (left), model (black) and measured rotation curves (middle), joint i−v_2.2 distribution (right, shown as 1, 2, and 3 standard deviation contours). Bottom: observed velocity field (left), model (middle), and residuals (right). The red line indicates the location of 2.2l_sc. The velocity scale is the same in all panels.
