Moment-zero maps of the observed CO isotopologue transitions. From top to bottom are shown the ¹²CO, ¹³CO, and C¹⁸O isotopologues, while from left to right are shown the J=2-1, J=3-2, and J=6-5 transitions. The beams are displayed in the lowerleft, while the approximate location of the host star is given by the white star. The ¹²CO colour maps are displayed using a power-law scaling with an exponent of 0.5.
