candidates, including most of the galaxies previously reported within 10$^{\circ}$ of the Coma cluster by @2015ApJ...798L..45V and @2016ApJS..225...11Y, using a relatively small area of the total survey ($334$ deg$^2$). SMUDGes has now analyzed the SDSS Stripe 82 region and identified 172 candidate in this region, which is a much more typical region of the sky than that around the Coma cluster (Zaritsky et al. in prep.).

The limited passbands of the Legacy survey preclude stellar population modeling and spectroscopic observations of the SMUDGes candidates will always be highly limited [@2017ApJ...838L..21K Kadowaki et al., in prep]. Interestingly, the requirement of large , multi-passband imaging in the study of intersects with the interest of several ongoing cosmological surveys, such as the [, @2014arXiv1403.5237B], the and the [, @2019MNRAS.489..241M]. Here we explore the synergy between ands to perform the first statistical study of the stellar populations of UDG candidates over an area of sky that is not dominated by high density environments. Despite limited overlap within Stripe 82 between the two surveys, we were able to study a sample of 100 UDG candidates and perform the largest detailed population study of these galaxies to date.
