cds-question@unistra.frgalaxiescatalogssurveysgalaxy-classification-systemsinfrared-photometryvisible-astronomybroad-band-photometryextinctionWe present 226 large ultra-diffuse galaxy (UDG) candidates (r_e_>5.3, {mu}_0,g_>24mag/arcsec^2^) in the SDSS Stripe 82 region recovered using our improved procedure developed in anticipation of processing the entire Legacy Surveys footprint. The advancements include less constrained structural parameter fitting, expanded wavelet filtering criteria, consideration of Galactic dust, estimates of parameter uncertainties and completeness based on simulated sources, and refinements of our automated candidate classification. We have a sensitivity ~1mag fainter in {mu}_0,g_ than the largest published catalog of this region. Using our completeness-corrected sample, we find that (1) there is no significant decline in the number of UDG candidates as a function of {mu}_0,g_ to the limit of our survey (~26.5mag/arcsec^2^); (1) bluer candidates have smaller Sersic n; (3) most blue (g-r<0.45mag) candidates have {mu}_0,g_<~25mag/arcsec^2^ and will fade to populate the UDG red sequence we observe to ~26.5mag/arcsec^2^; (4) any red UDGs that exist significantly below our {mu}_0,g_ sensitivity limit are not descendent from blue UDGs in our sample; and (5) candidates with lower {mu}_0,g_ tend to smaller n. We anticipate that the final SMUDGes sample will contain ~30 x as many candidates.2021ApJS..257...60Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/257/60CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/371 : The Dark Energy Survey (DES): Data Release 2 (Abott+, 2021)J/ApJS/105/209 : Low surface brightness galaxies.
