Metallicities obtained for the single stars observed in 1999 December and 2001 February that have the highest probability of belonging to M35 (Prob+ members). The unfilled histogram represents the distribution of metallicities obtained for all of them, whereas the filled histogram only includes the hottest stars in this sample. We used the values corresponding to the hottest ones to derive a metallicity of [Fe/H] = −0.26 ± 0.09 for M35.
