Notes. Column 2 presents the total sample, and Cols. 3–5 present different redshift ranges. We define red quasars (rQSO) as those with a g* − i* color value in the upper 10th percentile of the SDSS DR7 quasar catalog g* − i* color values, while all BAL quasars were inspected visually. All quasars between the upper and lower 10 percentiles are defined as not-red quasars.
