Image Details
Caption: Figure 15.
CN emission maps enhanced by the subtraction of the azimuthal median. Details are the same as Figure 12. The position of 2I is indicated by the red cross. The featureless images indicate uniform CN emission around the optocentre. The criss-cross pattern is an artifact from the IFU borders when fewer than four exposures were coadded.
