Galaxy And Mass Assembly (GAMA): Assimilation of KiDS into the GAMA
  database
  The Galaxy And Mass Assembly Survey (GAMA) covers five fields with highly
complete spectroscopic coverage ($>95$ per cent) to intermediate depths
($r<19.8$ or $i < 19.0$ mag), and collectively spans 250 square degrees of
Equatorial or Southern sky. Four of the GAMA fields (G09, G12, G15 and G23)
reside in the ESO VST KiDS and ESO VISTA VIKING survey footprints, which
combined with our GALEX, WISE and Herschel data provide deep uniform imaging in
the $FUV\,NUV\,ugriZYJHK_s\,W1\,W2\,W3\,W4\,P100\,P160\,S250\,S350\,S500$
bands. Following the release of KiDS DR4, we describe the process by which we
ingest the KiDS data into GAMA (replacing the SDSS data previously used for
G09, G12 and G15), and redefine our core optical and near-IR catalogues to
provide a complete and homogeneous dataset. The source extraction and analysis
is based on the new ProFound image analysis package, providing matched-segment
photometry across all bands. The data are classified into stars, galaxies,
artefacts, and ambiguous objects, and objects are linked to the GAMA
spectroscopic target catalogue. Additionally, a new technique is employed
utilising ProFound to extract photometry in the unresolved MIR-FIR regime. The
catalogues including the full FUV-FIR photometry are described and will be
fully available as part of GAMA DR4. They are intended for both standalone
science, selection for targeted follow-up with 4MOST, as well as an
accompaniment to the upcoming and ongoing radio arrays now studying the GAMA
$23^h$ field.
