Mollweide projections of the 95 TITANS benchmark stars: 48 dwarfs (TITANS I, stars) and 47 giants (TITANS II, present work, circles). Left: In equatorial coordinates, colour-coded by the index colour B – V, the size of the star depends on the apparent G magnitude: the larger the brighter. Right: In galactic coordinates, colour-coded by the metallicity determined in this work (see Table 2), the size of the star scales with the Gaia parallax.
