The Hubble Legacy Fields (HLF-GOODS-S) v1.5 Data Products: Combining
  2442 Orbits of GOODS-S/CDF-S Region ACS and WFC3/IR Images
  We have submitted to MAST the 1.5 version data release of the Hubble Legacy
Fields (HLF) project covering a 25 x 25 arcmin area over the GOODS-S (ECDF-S)
region from the HST archival program AR-13252. The release combines exposures
from Hubble's two main cameras, the Advanced Camera for Surveys (ACS/WFC) and
the Wide Field Camera 3 (WFC3/IR), taken over more than a decade between
mid-2002 to the end of 2016. The HLF includes essentially all optical (ACS/WFC
F435W, F606W, F775W, F814W and F850LP filters) and infrared (WFC3/ IR F098M,
F105W, F125W, F140W and F160W filters) data taken by Hubble over the original
CDF-S region including the GOODS-S, ERS, CANDELS and many other programs (31 in
total). The data has been released at https://archive.stsci.edu/prepds/hlf/ as
images with a common astrometric reference frame, with corresponding inverse
variance weight maps. We provide one image per filter of WFC3/IR images at 60
mas per pixel resolution and two ACS/WFC images per filter, at both 30 and 60
mas per pixel. Since this comprehensive dataset combines data from 31 programs
on the GOODS-S/CDF-S, the AR proposal identified the MAST products by the
global name "Hubble Legacy Field", with this region being identified by
"HLF-GOODS-S". This dataset complements that of the Frontier Fields program.
The total incorporated in the HLF-GOODS-S is 5.8 Msec in 7211 exposures from
2442 orbits. This is ~70% of a HST full cycle!
