a) Overlay of CO(3–2) isovelocity contours that span the range (–180 km s^-1, 180 km s^-1) in steps of 30 km s^-1 on a false-color velocity map (linear color scale as shown). Velocities refer to v_sys(HEL) = 1127 km s^-1. b) Same as a) but zooming in on the CND region with a 20 km s^-1 – velocity spacing. c) Same as b) but derived from the CO(6–5) data. d) Overlay of the CO(3–2) line widths (FWHM) shown in contours (10, 30, 50 to 200 km s^-1 in steps of 30 km s^-1) on a false-color width map (logarithmic color scale as shown). e) Same as d) but zooming in on the CND region. f) Same as e) but derived from the CO(6–5) data.
