The m₅₀ depth achieved for the TNO (blue) and MBA (orange) searches as a function of the SNR of the input catalog choosing ﹩{N}_{{\rm{\min }}}﹩ such that the number of results per detector is fixed at 200. The solid black line represents a single-epoch SNR ∼ 5 limiting magnitude of m₅₀ = 23.7, while the dashed black line represents the theoretical optimal achievable coadded depth of ﹩{m}_{50}^{{\rm{coadd}}}=26.2﹩. The dotted black line visualizes the expected scaling of achieved depth with SNR, extrapolated from the single-epoch limiting magnitude.
