Page History
The cluster candidates were selected primarily based on their high-magnification lensing properties. They were also vetted for other considerations. Comments and suggestions were considered.
- The clusters are known to be massive and highly efficient lenses.
- The clusters have several sets of known multiple image systems confirmed with spectroscopic redshifts.
- Most of the clusters have high-quality magnification maps based on data in hand.
- The clusters were selected based on initial estimates of the number counts of lensed high redshift sources detectable within the WFC3-IR FOV.
- The area enclosed interior to the critical curve for z~4-10 sources can be fully captured within a single pointing of WFC3-IR.
- Clusters with higher redshifts will have less area masked by cluster galaxies, fainter intracluster light, and less contamination in the parallel blank fields.

In addition to their lensing properties, we weighed the following additional criteria:
