Making use of the availability of multiple independent magnification models for each of the HFF clusters and alternatively treating one of the models as the "truth," we show that the median magnification factors from the v4 parametric models are typically reliable to values of 30-50, and in one case to 100. Using the median magnification factor from the latest v4 models, we estimate the UV luminosities of the 2534 lensed z~2-9 galaxies, finding sources as faint as -12.4mag at z~3 and -12.9mag at z~7. We explicitly demonstrate the power of the surface density-magnification relations {Sigma}(z) versus {mu} in the HFF clusters to constrain both distant galaxy properties and cluster lensing properties. Based on the {Sigma}(z) versus {mu} relations, we show that the median magnification estimates from existing public models must be reliable predictors of the true magnification {mu} to {mu}<15 (95% confidence). We also use the observed {Sigma}(z) versus {mu} relations to derive constraints on the evolution of the luminosity function faint-end slope from z~7 to z~2, showing that faint-end slope results can be consistent with blank-field studies if, and only if, the selection efficiency shows no strong dependence on the magnification factor {mu}. This can only be the case if very low-luminosity galaxies are very small, being unresolved in deep lensing probes.2022ApJ...931...81Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/931/81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/127/2856 : Brown dwarfs in the 2MASS Survey (Burgasser+, 2004)J/AJ/132/1729 : Hubble Ultra Deep Field BVI-dropout sources (Beckwith+, 2006)J/ApJ/728/27 : Chandra and AAOmega observations of Abell 2744 (Owers+, 2011)J/ApJ/762/L30 : MCS J0416.1-2403 strong lensing analysis (Zitrin+, 2013)J/MNRAS/444/268 : HST Frontier Fields clusters (Richard+, 2014)J/ApJ/800/18 : HST/WFC3 obs. of z~7-8 galaxies in A2744 (Atek+, 2015)J/ApJ/803/34 : z~4-10 galaxies from HST legacy fields (Bouwens+, 2015)J/ApJS/221/23 : IRAC HUDF and GOODS ultradeep surveys (Labbe+, 2015)J/ApJS/219/15 : Morphologies of z=0-10 galaxies with HST (Shibuya+, 2015)J/ApJ/801/44 : HST lensing analysis of the CLASH sample (Zitrin+, 2015)J/ApJ/819/114 : Strong lensing mass modeling of 4 HFF cl.
