VI color-magnitude diagram for NGC 4815 from Prisinzano et al. (2001) with stars observed by Gaia-ESO Survey indicated. Panel a) stars observed with UVES indicated with red squares. GIRAFFE targets are indicated with green diamonds. An additional 39 targets are not shown as they are lacking VI photometry. Panel b) cluster members on the basis of radial velocity determination are indicated with filled red squares (for UVES targets) and filled blue diamonds (for GIRAFFE targets). Stars with velocities differing more than 4 km s^-1 from the cluster mean are indicated with open symbols.
