Integrated-intensity (moment-zero) maps of the molecular lines detected in IRAS 23304+6147. The white ellipse in the lower corner represents the synthesized beam. For convenience, the dashed elliptical circles in each panel indicate the main CO emission region, whose semimajor (PA = 30°) and minor axis (PA = 60°) are 1.16″ and 0.84″, and the dashed straight lines mark the size of the extended CO halo. The NW direction is marked in the upper left corner of the CO map.
