Compiled in the course of the Massive Cluster Survey project (MACS) that detected the FF clusters, this catalog is provided to the community for three purposes: (1) to allow the identification of cluster members for studies of the galaxy population of these extreme systems, (2) to facilitate the removal of unlensed galaxies and thus reduce shear dilution in weak-lensing analyses, and (3) to improve the calibration of photometric redshifts based on both ground- and spacebased observations of the FF clusters.</description><source format="bibcode">2014ApJS..211...21E</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/211/21</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/VII/4">VII/4 : Abell and Zwicky Clusters of Galaxies (Abell+ 1974)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/406/1318">J/MNRAS/406/1318 : Lensed-arc statistics of galaxy clusters (Horesh+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/404/325">J/MNRAS/404/325 : Massive galaxy clusters lensing analyse (Richard+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/191/340">J/ApJS/191/340 : Southern Cosmology Survey.
