Stellar streams detection rate as a function of the image surface brightness limit for the TNG50 simulation. The percentage of the streams detected by visual inspection is plotted versus the surface brightness limit at which such detection was possible. The solid line corresponds to a stellar mass range of log₁₀M_⋆/M_⊙ = 10.48 and log₁₀M_⋆/M_⊙ = 10.76, while the dashed line corresponds to an extended mass range up to log₁₀M_⋆/M_⊙ = 10.9.
