Caption: Figure 1.

The spatial distribution of the CN fluxes on the IFU FOV is shown. The position of the optocenter of 3I, on the edge of the IFU, is denoted by an X. The CN fluxes are determined every 1″, or 1327 km. The tail direction marked is just the extended heliocentric radius vector as we did not actually see a tail. We mark the direction of motion.
