These clusters are massive (M_500c > 6.0 x 10e14Msol) and reveal a large lensing cross-section, having an Einstein radii of 46'', 49'', 52'' and showing multiple concentric arcs. Our proposed use of HST data will allow us to suitably map the dark matter and build a reliable strong lensing model due to their apparently smooth mass distribution (as opposed to most of HFF clusters) and significant number of lensing constraints. In addition, giant arcs (e.g. 21'' in extent, and some very bright) promise significant science impact once the lensing model has been ''focused''. By observing those targets we will calibrate new cosmic telescopes for JWST. In our proposed observations, we lay the groundwork for the best outcome possible by targeting obviously spectacular lensing cluster promoting high-redshift studies of the magnified background universe with JWST. ------------------------------------------------------------------------------------ Observations Description ------------------------ To be Reviewed: We request to observe each cluster with four filters, using in 3 orbits of HST time: one orbit each with the ACS/F606W filter, one orbit with the ACS/F814W filter, and one orbit with WFC3/IR split between two filters, F105W and F140W. This brings the total request to 9 orbits. Using the ETC, we conservatively estimate a 5 point source detection of 27.1 mag in F606W, 26.5 mag in F814W, and 26 mag in each of the IR filters The exact magnitudes depend on the actual visibility time and source spectral energy distribution; For our targets, the APT estimates 53-54 minutes per orbit, and we made these estimates for a flat spectrum. 15937( 4) -
