Plot used to determine the mass of α Cen A. The colours give the masses of the lines ranging from 0.7 M_⊙ (black) in the right of the figure in steps of 0.1 M_⊙ to 1.3 M_⊙ (magenta/purple) in the left of the figure. The different line types give the metallicity. The star shows the location of α Cen A in the figure. The shaded area in the top indicates the region where another mass plot would be more suitable.
