Moment zero (left), one (middle), and two (right) of the HCO(4–3) cube with 0.019″ beam toward NGC 613. The moments have been integrated over a velocity range from −260 to 260 km s⁻¹, and with a threshold of 2.2 mJy beam⁻¹. In the middle, the color scale is in velocity difference from the V_sys = 1481 km s⁻¹. The synthesized beam is shown in the bottom left corner of right box. The spatial scales are RA-Dec in arc seconds, from the central position reported in Table 1.
