Description

Single Sersic profile fits for 29,608 sources over Abell 2744, in all 20 NIRCam bands

authors: Yunchong Zhang, Tim Miller, Sedona Price, Wren Suess, Rachel Bezanson, David Setton, and the UNCOVER/MegaScience Collaboration

The sersic parameters and associated uncertainties are estimated with pysersic. The fitting targets are selected by requiring SNR>10 in the given band, using the UNCOVER/MegaScience photometric catalog. We additionally fit these observed sizes (flagged as robust or great quality) as a function of wavelength. Using the redshift posterior distribution from the UNCOVER/MegaScience SPS catalog, we infer rest-frame sizes for each available case at UV (0.3 micron), optical (0.5 micron), and NIR (1 micron), which are included in the rest-frame size catalog. See README or the catalog release paper (to be released) for details.
