Velocity maps and models of examples of a FR (left) and a SR (right), with raw data (top), a reconstructed velocity field employing a pure cosine law along ellipses (middle), and residuals depicting deviations (bottom). Our visualization emphasizes structural features through isodensity ellipses spaced at regular R_e intervals from R_e to 3R_e. The major axis orientations – with solid lines representing photometrically derived morphological axes and dashed lines indicating kinematically determined axes – are both measured at R_e.
