(Z−J, Z) colour−magnitude diagram for all objects in the AAOmega field-of-view (crosses) along with the new USco candidate members presented in this paper (filled dots) and photometric candidates lacking spectroscopy (open squares around filled dots). Overplotted are the nine objects classified as proper motion non-members by Lodieu et al. (2007b) and reclassified as spectroscopic members here (blue open triangles). Open red triangles represent a sample of stars in the AAOmega field classified as photometric non members but with proper motions and equivalent width measurements consistent with young objects. Open green diamonds represent the four photometric candidates rejected as spectroscopic members after our AAOmega follow-up.
