Comparison of the surface brightness limit (3σ, 10 × 10 arcsec²) for the Euclid/VIS Wide Survey (and two magnitudes deeper for the Deep Fields), compared with a selection of deep optical and near-infrared surveys including SDSS (York et al. 2000), IAC Stripe 82 (S82 Fliri & Trujillo 2016), the MATLAS deep-imaging Survey (Duc et al. 2015), DECaLS (Dey et al. 2019), Stellar Tidal Stream Survey (Martínez-Delgado 2019, STSS), Hyper Suprime-Cam DR2 (Aihara et al. 2018), Coma Cluster Dragonfly observations (van Dokkum et al. 2020), HST WFC3 ABYSS HUDF (Borlaff et al. 2019), XDF (Illingworth et al. 2013), UGC00180 10.4 m GTC exploration (Trujillo & Fliri 2016), the Burrell Schmidt Deep Virgo Survey (Mihos et al. 2017), the VEGAS-VST (Iodice et al. 2020; Ragusa et al. 2021), and LSST (10-year full survey integration, Ivezić et al. 2019).
