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:

Also please visit the Spitzer Frontier Fields website for access to all the Spitzer data on the Frontier Fields.

Latest news:
Feb 28, 2013: HST V1.0 mosaics released for Epoch 1 of MACSJ0416.1-2403

We are pleased to announce the Version 1.0 release of MACSJ0416.1-2403, after the successful completion of our first epoch of ACS imaging on the main cluster and WFC3/IR imaging on the parallel field from our Frontier Fields program (13496, PI: J. Lotz), combining also with additional imaging from the CLASH program 12459 (PI: M. Postman), and from the supernova program 13386 (PI: S. Rodney).

These v1.0 mosaics include all the ACS and WFC3/IR primary and parallel data obtained on this field to date, and have been fully recalibrated relative to the v0.5 mosaics that we released each week throughout the course of this epoch. For ACS, the v1.0 mosaics incorporate new bias and dark current reference files, along with CTE correction and bias destriping. The WFC3/IR v1.0 mosaics have improved masking for persistence and bad pixels, and in addition 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. We have also refined the astrometric corrections and masking for satellite trails, bad pixels and other defects. We also are releasing an additional "beta" reduction of ACS mosaics on the parallel field that have been created with a new self-calibration approach. All the v1.0 mosaics can all be obtained from the following location:

Access to all HST data on these fields:

  • Via your browser:
    http://archive.stsci.edu/pub/hlsp/frontier/ is the starting navigation point to all the data on these clusters.
  • FTP:
    ftp archive.stsci.edu and login as anonymous.
    cd /pub/hlsp/frontier
    From there you can navigate through the site to find the field and data of interest.
  • WGET
    You can download whole directories of data using wget commands like:
    wget -nH --cut-dirs=5 -r -l0 -c -N -np -R 'index*' -erobots=off http://archive.stsci.edu/pub/hlsp/frontier/macs0416/images/hst/
