Excitation and ionization equilibria of Ti and Fe lines, resulting from the new set of atmospheric parameters for HE 0240-0807. The black dots are the abundances obtained from Ti i and Fe i lines, and the red squares are those from Ti ii and Fe ii lines; the black dotted lines represent the average metallicity from the neutral species, and the red dotted lines represent the average metallicity from the ionized species.
