Hubble Legacy Fields ("HLF")

The Hubble Legacy Fields project combines exposures from Hubble's two main workhorse cameras (ACS/WFC and WFC3) for the GOODS-South (ECDF-S) region from the HST archival program AR-13252. The observations were 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-South region including the GOODS-South, CANDELS, ERS, ECDF-S and many other programs. Given that this dataset combines all images in the archive on the CDF-S to date, the AR proposal identified the product under the global name "Hubble Legacy Field". Given the large area, a global astrometric solution was bootstrapped from the smaller datasets. All the image mosaics have been produced using the same tangent point as the original GOODS-S dataset. The total incorporated in the HLF-GOODS-S is 5.8 MSec in 7211 exposures from about 2442 orbits.
