Description: Imaging observations of RDCS J1252.9-2927 in the optical have been carried out from the ground and from space. The ACS Wide Field Camera (WFC) on HST was used to obtain imaging with the F775W and F850LP filters (hereafter i775 and z850, respectively), as part of a guaranteed time observation program (ObsID 9290). Three orbits in i775 and five orbits in z850 were completed during 2002 May and June. The ground-based optical data were collected with FORS2 on the VLT, under ESO program 169.A-0458(A). The imaging data in the B, V, and R bands were obtained between 2003 March 1 and March 3. Ground-based near-IR imaging observations of RDCS J1252.9-2927 were taken with ISAAC on the ESO VLT and are described in Lidman et al. (2004A&A...416..829L) . File Summary:
