Issue Date: | 2021 | Journal: | RESEARCH NOTES OF THE AAS | Number: | 5 | Issue: | 8 | First Page: | 190 | Abstract: | We present the optimal resolution and optimal depth U-filter mosaics using the seeing-sorted method of Ashcraft et al. on deep, ground-based U-bandimaging of the Great Observatories Origins Deep Survey South field as part of the near-UV imaging program UVCANDELS. We use the U-bandimages obtained with the VIsible Multi-Object Spectrograph on the European Southern Observatory Very Large Telescope by Nonino et al. Our best resolution mosaic includes images with a seeing full-width half maximum (FWHM) ≤ 0"8, and encompasses 50% of the data. Our best depth mosaic includes images with FWHM ≤ 1"5, corresponding to 100% of the data. Prior to being combined, the source fluxes in each individual background-subtracted image are corrected to match a 3D-HST photometric catalog of the same field to correct variations in the U-band zero-points. These mosaics provide deep U-banddata complementary to the UVCANDELS HST WFC3 F275W and ACS F435W images. We assess the depth of both U-bandmosaics. * Based on data acquired using the Very Large Telescope (VLT) of the European Southern Observatory (ESO). | URI: | http://hdl.handle.net/20.500.12386/32049 | URL: | https://iopscience.iop.org/article/10.3847/2515-5172/ac1db6 | ISSN: | 2515-5172 | DOI: | 10.3847/2515-5172/ac1db6 | Bibcode ADS: | 2021RNAAS...5..190O | Fulltext: | open |
