The UNCOVER phot. catalog of A2744 with HST+JWST

Together with existing Hubble Space Telescope (HST) imaging, this publicly available data set opens a fundamentally new discovery space to understand the remaining mysteries of the formation and evolution of galaxies across cosmic time.

In this work, we detect and measure some 60000 objects across the 49arcmin^2^ JWST footprint down to a 5{sigma} limiting magnitude of ~30mag in 0.32" apertures. Photometry is performed using circular apertures on images matched to the point-spread function (PSF) of the reddest NIRCam broad band, F444W, and cleaned of bright cluster galaxies and the related intracluster light. To give an impression of the photometric performance, we measure photometric redshifts and achieve a {sigma}NMAD~0.03 based on known, but relatively small, spectroscopic samples.
