Abstract:
We present a set of photometric catalogues primarily aimed at
providing the community with a comprehensive database for the study of
galaxy populations in the high redshift Universe. The set gathers data
from eight JWST NIRCam observational programs, targeting the Abell
2744 (GLASS-JWST, UNCOVER, DDT2756 and GO3990), EGS (CEERS), COSMOS
and UDS (PRIMER), and GOODS North and South (JADES and NGDEEP) deep
fields, for a total area of 0.2 sq. degrees.
Photometric estimates are obtained by means of well-established
techniques, including tailored improvements designed to enhance the
performance on the specific dataset. We also include new measurements
from HST archival data, thus collecting 16 bands spanning from 0.44 to
4.44um. Results. A grand total of 530 thousand sources is detected on
stacks of NIRCam 3.56 and 4.44um mosaics. We assess the photometric
accuracy by comparing fluxes and colours against archival catalogues.
We also provide photometric redshift estimates, statistically
validated against a large set of robust spectroscopic data.
The catalogues are publicly available on the Astrodeep website.
Description:
We presented and discussed a major release of photometric catalogs,
collecting data from eight JWST observational programs on six deep
extra-galactic fields. We release a new reduction of the Abell 2744
composite mosaics, gathering the GLASS-JWST, UNCOVER, DDT2756 and
GO3990 programs, and use the reductions provided by the teams of the
other programs. NIRCam data are complemented with archival HST images
on which we perform new measurements.
The catalogs, mainly conceived for high redshift science,
include a grand-total of 531173 objects, of which 17359 are tagged as
spurious, and 2268 more have bad photometric measurements (flag≥400,
see Section 3.5). Sources were detected with SExtractor on stacks of
the F356W and F444W mosaics of each field. For all the detections we
provide positions in equatorial and pixel coordinates, basic
morphological parameters, total fluxes and corresponding uncertainties
in 16 photometric bands computed by means of the software a-phot, a
diagnostic flag, and four photometric redshift estimates obtained with
zphot and EAzY.
Photometric parameters and photo-z estimates for galaxies in
ABELL2744, CEERS, JADES-GN, JADES-GS, NGDEEP, PRIMER-COSMOS and
PRIMER-UDS fields
The catalogs are publicly available on the Astrodeep website
(https://astrodeep.eu).
