Low resolution (but without the most compact configurations) at ∼0.1″ (left), zoomed in on the middle and high resolution at ∼0.015″ (right) of the CO(3–2) surface density toward NGC 613. The left and middle moment-0 maps have been integrated over a velocity range −175 to 175 km s⁻¹, and with a threshold of 2.3 mJy beam⁻¹. In the right panel, the CO(3–2) contours of the low-resolution map are overlaid. While the left panel is plotted in absolute coordinates, the spatial scales of the two others are RA-Dec offsets in arc seconds, from the center of Table 1. The color scale is in Jy beam⁻¹ km s⁻¹.
