HC3N J = 12–11 emission. Upper left panel: moment-0 map of HC3N emission. Top center panels: channel maps of the HC3N line; selected velocity channels are shown to highlight the Keplerian rotation of the disk. Bottom panel: matched-filter response spectrum for the full spectral window containing the HC3N J = 12–11 transition. The red dashed line marks the expected rest frequency of HC5N J = 41–40.
