Step by step procedure (from left to right) applied in the selection of candidate members. (a) V, B − V CMD for NGC 6705, showing the selection of candidate members. In grey we show all stars with optical photometry, while red filled triangles represent the stars selected on the basis of BV photometric information. The line is the best-fit PARSEC (Bressan et al. 2012) isochrone (see Cantat-Gaudin et al. 2014), while the black symbols are selected members from kinematic analysis (see Sect. 4). (b) The stars selected in the optical bands are shown in grey, in the V vs. J − K CMD; here red points represent the stars selected based on JHK analysis. (c) Candidate targets in grey, with kinematic outliers shown in green. (d) Final selection (in grey) is shown together with the stars actually observed (in red with GIRAFFE, in blue with UVES fibres).
