The Frontier Fields is a Spitzer and HST Director's Discretionary program of six deep fields centered on strong lensing galaxy clusters
in parallel with six deep "blank fields". These will be the second deepest observations of blank fields and
deepest observations of clusters and their lensed galaxies ever obtained.
The first data release contains all archival data taken on these six clusters as
well as data taken for the cycle-9 SURFS-UP (PID:90009) program as of April 1, 2013.
Improved reductions with better artifact correction and deeper data will be
released periodically over the three year period.
IRSA hosts the Spitzer portion of the Frontier Fields data set. For the HST Frontier Fields data, see
