Carbon isotopic ratios (panel (a)) and CNO abundances (panels (b)–(d)) as functions of Li abundance in all NGC 7789 program stars, including star 193, which is a probable nonmember of the cluster. The dotted lines in panels ((b)–(d)) indicate the solar abundance values. Star 193 is the blue dot and Star 301 is the red dot.
