The Hubble Legacy Field GOODS-S Photometric Catalog
  This manuscript describes the public release of the Hubble Legacy Fields
(HLF) project photometric catalog for the extended GOODS-South region from the
Hubble Space Telescope (HST) archival program AR-13252. The analysis is based
on the version 2.0 HLF data release that now includes all ultraviolet (UV)
imaging, combining three major UV surveys. The HLF data combines over a decade
worth of 7475 exposures taken in 2635 orbits totaling 6.3 Msec with the HST
Advanced Camera for Surveys Wide Field Channel (ACS/WFC) and the Wide Field
Camera 3 (WFC3) UVIS/IR Channels in the greater GOODS-S extragalactic field,
covering all major observational efforts (e.g., GOODS, GEMS, CANDELS, ERS,
UVUDF and many other programs; see Illingworth et al 2019, in prep). The HLF
GOODS-S catalogs include photometry in 13 bandpasses from the UV (WFC3/UVIS
F225W, F275W and F336W filters), optical (ACS/WFC F435W, F606W, F775W, F814W
and F850LP filters), to near-infrared (WFC3/IR F098M, F105W, F125W, F140W and
F160W filters). Such a data set makes it possible to construct the spectral
energy distributions (SEDs) of objects over a wide wavelength range from high
resolution mosaics that are largely contiguous. Here, we describe a photometric
analysis of 186,474 objects in the HST imaging at wavelengths 0.2--1.6$\mu$m.
We detect objects from an ultra-deep image combining the PSF-homogenized and
noise-equalized F850LP, F125W, F140W and F160W images, including Gaia
astrometric corrections. SEDs were determined by carefully taking the effects
of the point-spread function in each observation into account. All of the data
presented herein are available through the HLF website
