Abstract:
UltraVISTA is an ultra-deep near-infrared survey of the central region
of the COSMOS field (Scoville+ 2007ApJS..172..196K 2007ApJS..172..196K).
In this fourth release (DR4) we provide five stacked images and their
corresponding weight maps for Y JHKs and NB118 narrow-band data taken
during the first seven years of UltraVISTA survey operations. In
addition, single band individual source lists and source lists created
in dual-image mode (using the Ks image as a detection image) are
provided (note that in ESO terminology, single-band tabular data are
referred to as "Source lists" and multi-band merged data are referred
to as catalogues). We also provide a five-band catalogue that meets
the requirement for a catalogue in the Phase 3 framework. The data
volume is ∼90GB as in DR3. The total survey area is close to
1.9deg2.
Description:
DR4 was built from the pre-processed UltraVISTA images from CASU ("The
Cambridge Astronomy Survey Unit") observed at VISTA from 4 December,
2009 to 29 June, 2016 as available in early 2017.
We downloaded 63931 individual images. After quality control (which
mainly is a rejection of images with FWHM>1.0" or ellipticity>0.1), we
were left with 58138 individual images that were used to create the
5 stacks for the 5 bands: Y , J, H, Ks, and NB118. This release
comprises seven complete observing seasons: however, less data were
taken in season 2 (2010-2011) due to the VISTA primary mirror being
re-coated during the UltraVISTA observing season.
VISTA is a 4-m class wide-field survey telescope equipped with an IR
camera (VIRCAM) and located at ESO's Cerro Paranal Observatory in
Chile.
Note that, unlike in previous releases, chip 16 has not been masked.
