Fig. 3.

Selected channel maps from the low-resolution [C II] datacube binned to 40 km s⁻¹. Black contours represent 3, 5 and 7 times the JvM-corrected noise rms level, while the gray contours show the negative 3 × rms level. The purple cross in each channel indicates the origin of the coordinates, at $α_{ICRS} = 150 \overset{″}{.} 227063$ $\alpha_{\mathrm{ICRS}}=150{{\overset{\prime\prime}{.}}}227063$ , $δ_{ICRS} = 2 \overset{″}{.} 576679$ $\delta_{\mathrm{ICRS}}=2{{\overset{\prime\prime}{.}}}576679$ .
