Notes. Column 1: r-magnitude limit; the first SP and CP rows correspond to the full, not magnitude-limited samples. Column 2: OTELO-Deep image detection completeness from Bongiovanni et al. (2019). Column 3: sample size. Column 4: sample baseline. Columns 5–7: u − r, LDA and DNN accuracies, respectively, obtained after 100 bootstrap runs.
