Comparison of the surface brightness limit (3σ, 10 × 10 arcsec²) as a function of the observed area for a selection of deep optical and NIR surveys. Depths are measured in the r-band (noted when not applicable). The Stellar Stream Legacy Survey presented in this paper is indicated with a blue star. The other surveys comprise: Stellar Tidal Stream Survey (Martínez-Delgado 2019, STSS), Euclid VIS (Euclid Collaboration 2022a), SDSS (York et al. 2000), IAC Stripe 82 (Fliri & Trujillo 2016), the MATLAS deep imaging Survey (g-band magnitudes Duc et al. 2015), Hyper Suprime-Cam DR2 (Aihara et al. 2018), NGC 4565 Dragonfly observation (Gilhuly et al. 2020), HST WFC3 ABYSS HUDF (NIR bands Borlaff et al. 2019), XDF (Illingworth et al. 2013), UGC00180 10.4m GTC exploration (Trujillo & Fliri 2016), the Burrell Schmidt Deep Virgo Survey (Mihos et al. 2017), the CFIS/UNIONS survey (Sola et al. 2022), the VEGAS/VLT survey (Ragusa et al. 2021), and the Rubin Telescope Legacy Survey of Space and Time (10 yr full survey integration, Ivezić et al. 2019).
