Velocity map of the NGC 613 CO(3–2) line residuals, once the spectra have been fit by a Gaussian, inside the range −150 to 150 km s⁻¹, first at low resolution (left) and then at high resolution (right). Note that the field of view is different in the two panels (1″, and 0.1″, respectively). The contours of the CO(3–2) map at low resolution are overlaid in the left panel. The scale is RA-Dec offset in ″. The color scale is in km s⁻¹.
