Abstract:
We present images and a multiwavelength photometric catalog based on
all of the JWST NIRCam observations obtained to date in the region of
the Abell 2744 galaxy cluster. These data come from three different
programs, namely, the GLASS-JWST Early Release Science Program,
UNCOVER, and the Director's Discretionary Time program 2756. The
observed area in the NIRCam wide-band filters-covering the central and
extended regions of the cluster, as well as new parallel fields-is
46.5 arcmin2 in total. All images in eight bands (F090W, F115W, F150W,
F200W, F277W, F356W, F410M, and F444W) have been reduced adopting the
latest calibration and reference files available. Data reduction has
been performed using an augmented version of the official JWST
pipeline, with improvements aimed at removing or mitigating defects in
the raw images and improving the background subtraction and
photometric accuracy. We obtain an F444W-detected multiband catalog,
including all NIRCam and available Hubble Space Telescope data,
adopting forced-aperture photometry on point-spread- function-matched
images. The catalog is intended to enable early scientific
investigations and is optimized for the study of faint galaxies; it
contains 24,389 sources, with a 5σ limiting magnitude in the
F444W band ranging from 28.5 AB to 30.5 AB, as a result of the varying
exposure times of the surveys that observed the field. We publicly
release the reduced NIRCam images, associated multiwavelength catalog,
and the code adopted for 1/f noise removal with the aim of aiding
users in familiarizing themselves with JWST NIRCam data and
identifying suitable targets for follow-up observations.
Description:
The NIRCam data analyzed in this paper are taken from three programs
that targeted the z=0.308 cluster Abell 2744 and its surroundings.
The first set of NIRCam images was taken as part of the GLASS-JWST
survey (T22; Treu+ 2022ApJ...935..110T 2022ApJ...935..110T), in parallel to primary NIRISS
observations on 2022 June 28-29 and to NIRSpec observations on
2022 November 10-11. We refer to these data sets as GLASS1 and GLASS2,
or collectively as GLASS, both of which consist of imaging in seven
broadband filters from F090W to F444W. We note that the final pointing
is different from the scheduled one presented by T22 due to the
adoption of an alternate position angle (PA) during the NIRSpec
spectroscopic observations (see Section 2.1).
The second set of NIRCam observations considered here was taken as
part of the UNCOVER program (Bezanson+ 2024ApJ...974...92B 2024ApJ...974...92B), which
targets the center of the A2744 cluster and the immediate
surroundings. These images are composed of four pointings and result
in a relatively homogeneous depth, as discussed below. They were taken
on November 2-4-7 and 15 and adopt the same filter set as GLASS-JWST,
except for the addition of the F410M filter instead of F090W.
Finally, the Director's Discretionary Time program 2756 (PI: W. Chen;
DDT hereafter) also obtained NIRCam imaging data in the center of
A2744 on 2022 October 20 and December 6 (UT).
The data obtained by these three NIRCam programs are taken with eight
different filters (F090W, F115W, F150W, F200W, F277W, F356W, F410M,
and F444W).
We also exploit other HST publicly available programs that have
targeted the area, including the available HST ACS and WFC3 data in
the F435W, F606W, F775W, and F814W (ACS) and F105W, F125W, F140W, and
F160W (WFC3) bands, to expand the coverage of the visible-to-IR
wavelength range.
We have first used SExtractor to detect sources in the F444W band and
measure their total flux in the same F444W band. We release catalogues
computed in 2x, 3x, 8x and 16x PSF apertures (diameter, which
correspond to 0.28", 0.42", 1.12" and 2.24") and in the isophotal
(segmentation) aperture. Note that all files contain the same
24389 objects in the same order.
