This is the primary Archive website for accessing all the Hubble Space Telescope Frontier Fields program data, which is a new initiative of six deep fields centered on strong lensing galaxy clusters (drawn from Abell et al. 1989) and the MACS survey (Ebeling et al. 2001), in parallel with six deep "blank fields" adjacent to these clusters. Please refer also to the main Frontier Fields project website where additional information is presented about the project, the team, and links to a blog. The program devotes 140 orbits to each cluster/blank field pair, imaging them to AB ≈ 28.7-29 mag with ACS (F435W, F606W, F814W) and and WFC3/IR (F105W, F125W, F140W, F160W). We are providing a variety of products for these clusters, including:

October 14, 2014: First new v0.5 HST mosaics released for Epoch 1 of MACSJ0717.5+3745

We are pleased to announce the release of the first new HST mosaics obtained on the cluster MACSJ0717.5+3745, from the observations of this target from our Frontier Fields program ID 13498 (PI: J. Lotz), which also includes archival ACS and WFC3/IR data (programs 9722 and 10420, PI.: H. Ebeling; programs 10493 and 10793, PI.: A. Gal-Yam; program 12103, PI.: M. Postman; program 13389, PI.: B.Siana; and program 13459, PI.: T. Treu), to provide the most complete full-depth mosaics in the ACS/WFC and WFC3/IR filters that are used for the Frontier Fields program, where all data have been fully reprocessed using the most current calibration files. These mosaics have all been processed beyond the default pipeline calibration, in order to produce the best possible quality, science-ready full-depth mosaics. For ACS, these mosaics incorporate CTE correction and bias destriping, as well as a set of mosaics that have been processed with the new selfcal approach to better correct for low-level dark current structure. The WFC3/IR mosaics have been masked for persistence and bad pixels, and in addition include a set of mosaics that have been corrected for time-variable sky emission that can occur during the orbit and can otherwise impact the up-the-ramp count-rate fitting if not properly corrected. All these mosaics are aligned to a common pixel grid as well as to an absolute astrometric frame based on pre-existing catalogs of this field. Further details are provided in the readme file, which can be obtained along with all the mosaics at the following link:
