Notes. The columns contain the following: (1) stellar population model; for B07 models the number is as in the original paper; (2) approximate age of the dominant star-formation epoch(s); (3) average metallicity of the stars; (4)–(6) mass-to-light ratio in the gri filters; (7) total stellar mass fraction in M 31 of the corresponding stellar population.
