Schematic view of the UKIDSS GCS coverage in IC 4665 is shown with thick solid lines. We included known high probability photometric candidates (star symbols) from Prosser (1993), the optical (I,z) candidates de Wit et al. (2006) confirmed (filled circles) and rejected (plus symbols) by the GCS photometry, as well as new photometric candidates identified in the GCS outside the optical coverage (open triangles). A more detailed view of the optical coverage is shown in Fig. 2 of de Wit et al. (2006).
