Abstract:
We present the multiwavelength photometry of two Frontier Fields
massive galaxy clusters, MACS-J0717 and MACS-J1149, and their parallel
fields, ranging from Hubble Space Telescope (HST) to ground-based K
and Spitzer IRAC bands, and the public release of photometric
redshifts and rest-frame properties of galaxies found in cluster and
parallel pointings. This work was carried out within the ASTRODEEP
project and aims to provide a reference for future investigations of
extragalactic populations.
To fully exploit the depth of the images and detect faint sources, we
used an accurate procedure, which carefully removes the foreground
light of bright cluster sources and the intra-cluster light thus
enabling detection and measurement of accurate fluxes in crowded
cluster regions. This same procedure has been successfully used to
derive the photometric catalogue of MACS-J0416 and Abell-2744.
The obtained multiband photometry was used to derive photometric
redshifts, magnification, and physical properties of sources. In line
with the first two FF catalogues released by ASTRODEEP, the
photometric redshifts reach ∼4% accuracy. Moreover we extend the
presently available samples to galaxies intrinsically as faint as
H160∼32-34mag thanks to the magnification factors induced by strong
gravitational lensing. Our analysis allows us to probe galaxy masses
larger than 107M☉ and/or SFR=0.1-1M☉/yr out to redshift
z>6.
Description:
M0717 and M1149 are the third and fourth of a total of six twin fields
observed by HST in seven optical and near-infrared bands: F435W,
F606W, and F814W from ACS/WFC and F105W, F125W, F140W, and F160W from
WFC3/IR. Each of these fields is observed by HST in parallel mode,
i.e. cluster and a blank adjacent field.

Note (1): Sources with RELFLAG=1 Have enough reliable photometric information
for estimating photometricredshifts. Instead, the value is =0 for sources
either: falling close to the border of the images; close to strong residual
features of the Galfit image pre-processing; found to be spurious (mostly
stellar spikes) from visual inspection; having SExtractor FLAG≤16; having
unphysical flux in the detection band; having less than 5 HST bands with
reliable flux measurement available for photo-z procedures.
