Spite et al. (1988) compared the chemical composition of the atmospheres of three F supergiants in the SMC to the chemical composition of the Galactic supergiant Canopus. In this paper, equivalent widths for the stars, AZ 140, AZ 197, and AZ 369, are presented along with the derived abundance, line by line. Various physical constants of the lines are presented. Equivalent widths of the corresponding lines in Canopus from other studies are also given. A spectrum of Canopus in the red is used to determine the aluminum abundance.
