Proper-motion diagram for NGC 2345. Left: grey dots are the Gaia sources within 10′ around the nominal cluster centre, whereas coloured circles represent stars observed spectroscopically in this work: in blue, likely members previously cited in the bibliography and in green, field stars. The red square draws the boundary of the cluster according to that described in the text. Right: for clarification purposes only, Gaia sources are represented: the cluster clearly stands out from the background.
